## Summary [TSPAN31](/details-gene/6302), or tetraspanin 31, is a protein-coding gene located on chromosome 12q14.1. As a member of the transmembrane 4 superfamily, it is an integral membrane protein localized to the [plasma membrane](/details-cell/GO:0005886). Functionally, [TSPAN31](/details-gene/6302) is implicated in [protein binding](/details-cell/GO:0005515) and the [positive regulation of cell population proliferation](/details-cell/GO:0008284). Its expression profile is diverse, showing high significance in [epithelial cell of lung](/details-cell/CL0000082), developing B lymphocytes such as the [pro-B cell](/details-cell/CL0000826), and specialized neuronal cells like the [rod bipolar cell](/details-cell/CL0000751). Notably, this gene was first identified as Sarcoma-Amplified Sequence (SAS) due to its amplification in human sarcomas, suggesting a potential role in oncogenesis ([Link](https://pubmed.ncbi.nlm.nih.gov/8134123/)). It is clinically associated with OMIM entry [181035](https://omim.org/entry/181035). ## Cellular Roles and Expression Landscape The expression pattern of [TSPAN31](/details-gene/6302) suggests it has pleiotropic roles across multiple distinct biological systems. - **Epithelial and Structural Tissues:** **Overall**, the gene shows its highest significance in the [epithelial cell of lung](/details-cell/CL0000082) (CSI: 10.07), with notable expression also found in the [epithelial cell of lower respiratory tract](/details-cell/CL0002632) and [multi-ciliated epithelial cell](/details-cell/CL0005012). This strong association with pulmonary epithelia suggests a role in maintaining the structure, function, or regenerative capacity of the lung barrier. Its expression in [bronchus fibroblast of lung](/details-cell/CL2000093) further supports a function within the lung tissue microenvironment. - **Immune System:** [TSPAN31](/details-gene/6302) is a significant marker in the B lymphocyte lineage, with very high importance in the [pro-B cell](/details-cell/CL0000826) (CSI: 9.18) and continued relevance in the more differentiated [plasmablast](/details-cell/CL0000980). This pattern suggests a role in the early stages of B cell development and proliferation. Its expression in [group 3 innate lymphoid cell](/details-cell/CL0001071) and [CD4-positive helper T cell](/details-cell/CL0000492) indicates a broader involvement in both innate and adaptive immunity. - **Nervous System:** A highly specific expression pattern is observed in the retina, where [TSPAN31](/details-gene/6302) is a key marker for the [rod bipolar cell](/details-cell/CL0000751) and [ON-bipolar cell](/details-cell/CL0000749). This points towards a specialized function in retinal signal processing, potentially related to the organization of synaptic structures. - **Development:** The gene's high significance in [mesodermal cell](/details-cell/CL0000222)s indicates a role during embryonic development, consistent with its function in regulating cell proliferation. ## Pathways and Molecular Function [TSPAN31](/details-gene/6302) encodes a quintessential tetraspanin that resides in the [plasma membrane](/details-cell/GO:0005886). Tetraspanins are known to function as molecular organizers, scaffolding other proteins into membrane microdomains, which is consistent with the gene's annotated molecular function of [protein binding](/details-cell/GO:0005515). The primary biological process associated with [TSPAN31](/details-gene/6302) is the [positive regulation of cell population proliferation](/details-cell/GO:0008284). This function provides a direct molecular explanation for its initial discovery as a gene amplified in sarcomas ([Link](https://pubmed.ncbi.nlm.nih.gov/8134123/)) and its location within a chromosomal region frequently amplified in human cancers ([Link](https://doi.org/10.1006/geno.1997.4727)). Its role in proliferation may be central to its significance in highly proliferative cell types such as the developing [pro-B cell](/details-cell/CL0000826) and in the context of tissue repair or cancer in lung epithelial cells. ## Research Directions The diverse expression profile of [TSPAN31](/details-gene/6302), combined with its established link to cell proliferation and cancer, provides several avenues for future research. **Proposed Hypotheses:** 1. Given its high expression in lung epithelia and its pro-proliferative function, [TSPAN31](/details-gene/6302) may be a critical regulator of alveolar repair following injury, with its aberrant overexpression contributing to the development or progression of non-small cell lung cancer. 2. Based on its significance in early B-cell development, [TSPAN31](/details-gene/6302) could function as a modulator of signaling pathways that govern the transition from pro-B to pre-B cell stages, and its dysregulation may contribute to B-cell acute lymphoblastic leukemia. 3. In the retina, the specific expression of [TSPAN31](/details-gene/6302) in bipolar cells suggests it is required for the structural or functional integrity of synapses between photoreceptors and bipolar cells, potentially by organizing neurotransmitter receptors or adhesion molecules. **Experimental Approach:** To test the first hypothesis regarding its role in lung pathology, a valuable experiment would be to use a lung epithelial-specific, inducible knockout mouse model (e.g., Sftpc-CreERt2; Tspan31-fl/fl). These mice could be subjected to lung injury models, such as bleomycin administration, to assess the impact of [TSPAN31](/details-gene/6302) deletion on epithelial regeneration and fibrosis development via histology and single-cell RNA sequencing. Furthermore, crossing this model with a lung adenocarcinoma model (e.g., Kras-LSL-G12D) would directly test its role as a driver or modifier of tumorigenesis. **Therapeutic Potential:** As a cell surface protein with a role in promoting proliferation, [TSPAN31](/details-gene/6302) presents a promising therapeutic target, primarily for **inhibition**. Its documented amplification in sarcomas makes it an attractive candidate for targeted therapies in that context. Given its membrane location, it is particularly well-suited for antibody-based therapeutics, such as antibody-drug conjugates (ADCs) or chimeric antigen receptor (CAR)-T cell therapy, which could specifically target and eliminate tumor cells overexpressing [TSPAN31](/details-gene/6302). However, its expression in healthy tissues, including the lung and retina, would require careful evaluation to manage potential on-target, off-tumor toxicities.
