## Summary [CELSR1](/details-gene/9620) (cadherin EGF LAG seven-pass G-type receptor 1) is a protein-coding gene located on chromosome 22q13.31. It encodes a large, atypical cadherin that functions as a G protein-coupled receptor (GPCR) and is a key component of the core planar cell polarity (PCP) signaling pathway ([Link](https://doi.org/10.1002/humu.21662)). Its primary functions involve mediating [cell-cell adhesion](/details-cell/CL0000151) ([GO:0098609](https://www.ebi.ac.uk/QuickGO/term/GO:0098609)) and establishing tissue organization during development, particularly in the nervous system and lungs. **Overall**, expression data reveals that [CELSR1](/details-gene/9620) is a highly significant marker for secretory epithelial cells, such as [goblet cells](/details-cell/CL0000160), and various neural cell types, including [astrocytes](/details-cell/CL0000127), reflecting its critical role in developmental morphogenesis and tissue architecture. ## Cellular Roles and Expression Landscape The expression profile of [CELSR1](/details-gene/9620) highlights its importance in two major biological systems: epithelial tissues and the central nervous system. **Overall**, its most significant expression is observed in specialized secretory and epithelial cells of the respiratory and digestive tracts. It is a top marker for [goblet cells](/details-cell/CL0000160) (CSI: 15.46), which are responsible for mucus production. High significance is also noted in [respiratory basal cells](/details-cell/CL0002633) (CSI: 7.79), [secretory cells](/details-cell/CL0000151) (CSI: 6.50), and various other lung epithelial cell types, including [lung secretory cells](/details-cell/CL1000272) and [multi-ciliated epithelial cells](/details-cell/CL0005012). This pattern suggests a fundamental role for [CELSR1](/details-gene/9620) in establishing and maintaining the organized, polarized structure of mucosal epithelia. In the nervous system, [CELSR1](/details-gene/9620) shows high significance in glial and progenitor cells. It is a prominent marker in [astrocytes](/details-cell/CL0000127) (CSI: 9.27), [neuroblasts](/details-cell/CL0000338) (CSI: 5.49), [glioblasts](/details-cell/CL0000030) (CSI: 4.82), and [ependymal cells](/details-cell/CL0000065) (CSI: 3.49). This expression pattern is consistent with its established function in [central nervous system development](/details-cell/CL0000338) ([GO:0007417](https://www.ebi.ac.uk/QuickGO/term/GO:0007417)) and [neuron migration](/details-cell/CL0001764) ([GO:0001764](https://www.ebi.ac.uk/QuickGO/term/GO:0001764)), where it helps guide cellular positioning and tissue formation. ## Pathways and Molecular Function [CELSR1](/details-gene/9620) is a multifunctional protein with roles in cell adhesion and signal transduction. Its molecular identity as a cadherin underpins its function in [homophilic cell adhesion](/details-cell/CL0000151) ([GO:0007156](https://www.ebi.ac.uk/QuickGO/term/GO:0007156)), while its seven-transmembrane structure confers [G protein-coupled receptor activity](/details-cell/CL0000151) ([GO:0004930](https://www.ebi.ac.uk/QuickGO/term/GO:0004930)). The primary signaling pathway associated with [CELSR1](/details-gene/9620) is the [Wnt signaling pathway, planar cell polarity pathway](/details-cell/CL0000151) ([GO:0060071](https://www.ebi.ac.uk/QuickGO/term/GO:0060071)). This pathway is crucial for coordinating cell orientation within a tissue plane, a process vital for development. This is reflected in its involvement in biological processes such as [establishment of planar polarity](/details-cell/CL0000151) ([GO:0001736](https://www.ebi.ac.uk/QuickGO/term/GO:0001736)), [neural tube closure](/details-cell/CL0000151) ([GO:0001843](https://www.ebi.ac.uk/QuickGO/term/GO:0001843)), and lung morphogenesis ([GO:0060490](https://www.ebi.ac.uk/QuickGO/term/GO:0060490)). Indeed, mutations in [CELSR1](/details-gene/9620) are associated with severe neural tube defects ([Link](https://doi.org/10.1002/humu.21662)). The protein also plays a role in regulating the cytoskeleton via [Rho protein signal transduction](/details-cell/CL0000151) ([GO:0007266](https://www.ebi.ac.uk/QuickGO/term/GO:0007266)), which is essential for translating external adhesion cues into internal cellular structure. ## Research Directions The established role of [CELSR1](/details-gene/9620) in developmental disorders, such as neural tube defects and hereditary lymphedema ([Link](https://doi.org/10.1186/s13221-016-0035-5)), underscores its clinical importance. Its specific expression pattern in mature tissues suggests it may also have homeostatic functions that are currently less understood. Based on the available data, several testable hypotheses can be proposed: 1. Given its high significance in [goblet cells](/details-cell/CL0000160) and other respiratory epithelial cells, loss-of-function variants in [CELSR1](/details-gene/9620) may disrupt the coordinated organization of the mucociliary escalator, leading to impaired mucus clearance and increased susceptibility to chronic respiratory diseases like asthma or COPD. 2. The high expression of [CELSR1](/details-gene/9620) in [astrocytes](/details-cell/CL0000127) suggests it is critical for establishing and maintaining the glial scaffold in the mature brain. Dysregulation of [CELSR1](/details-gene/9620) in astrocytes following brain injury may impair glial scar formation and neuronal recovery. To test the first hypothesis regarding respiratory function, a key experiment could involve the use of air-liquid interface (ALI) cultures of primary human bronchial epithelial cells. Using CRISPR-Cas9 to knock down [CELSR1](/details-gene/9620) expression, researchers could assess the impact on epithelial layer integrity, the spatial organization of [goblet](/details-cell/CL0000160) and [multi-ciliated epithelial cells](/details-cell/CL0005012) via immunofluorescence, and functional outcomes such as ciliary beat frequency and directed mucus transport. From a therapeutic perspective, [CELSR1](/details-gene/9620) presents a challenging target. The associated pathologies are primarily caused by loss-of-function mutations ([Link](https://doi.org/10.1002/ajmg.a.61269)), suggesting a need for activation or gene replacement therapies rather than inhibition. Due to the protein's large size and complex transmembrane structure, pharmacological activation is difficult. Therefore, its therapeutic potential is likely limited to gene therapy approaches for severe congenital disorders, which would require careful consideration of developmental timing and off-target effects.
