## Summary [ADAM23](/details-gene/8745) (ADAM metallopeptidase domain 23) is a protein-coding gene located on chromosome 2q33.3. It belongs to the ADAM (A Disintegrin And Metalloproteinase) family of proteins, which are type I transmembrane proteins known for their roles in cell-cell and cell-matrix interactions. Functionally, [ADAM23](/details-gene/8745) is implicated in '[cell adhesion](/details-cell/GO0007155)', particularly through '[integrin binding](/details-cell/GO0005178)', and possesses '[metallopeptidase activity](/details-cell/GO0008237)' ([Link](https://doi.org/10.1091/mbc.11.4.1457)). Expression data reveals that [ADAM23](/details-gene/8745) is a highly significant marker within the central nervous system, showing prominent expression across diverse neuronal subtypes, especially cortical interneurons and retinal neurons. This profile is consistent with its annotated roles in '[central nervous system development](/details-cell/GO0007417)' and its localization to the '[presynaptic membrane](/details-cell/GO0042734)'. ## Cellular Roles and Expression Landscape **Overall**, the expression profile of [ADAM23](/details-gene/8745) demonstrates a strong and specific association with the nervous system. The gene exhibits its highest significance in various subtypes of GABAergic cortical interneurons, including '[pvalb GABAergic cortical interneuron](/details-cell/CL4023018)' (CSI: 39.39), '[VIP GABAergic cortical interneuron](/details-cell/CL4023016)' (CSI: 36.86), and '[lamp5 GABAergic cortical interneuron](/details-cell/CL4023011)' (CSI: 33.10). This suggests a critical role for [ADAM23](/details-gene/8745) in the function or identity of these inhibitory neurons. In addition to interneurons, [ADAM23](/details-gene/8745) is also a significant marker for various glutamatergic neuron populations, such as the '[L2/3 intratelencephalic projecting glutamatergic neuron](/details-cell/CL4030059)' (CSI: 24.84) and '[L4 intratelencephalic projecting glutamatergic neuron](/details-cell/CL4030063)' (CSI: 20.57). Its significance extends to the retina, where it is highly expressed in '[rod bipolar cell](/details-cell/CL0000751)' (CSI: 21.84) and '[retinal ganglion cell](/details-cell/CL0000740)' (CSI: 20.70). This broad yet specific neuronal expression pattern, first noted in early studies ([Link](https://doi.org/10.1042/bj3340093)), underscores its fundamental importance in neural circuit development and maintenance. ## Pathways and Molecular Function The molecular functions of [ADAM23](/details-gene/8745) are deeply intertwined with its cellular localization and biological roles. As a member of the ADAM family, it possesses both adhesion and proteolytic capabilities. Its function in '[cell adhesion](/details-cell/GO0007155)' is mediated in part by '[integrin binding](/details-cell/GO0005178)', a mechanism that allows it to facilitate interactions between cells and the extracellular matrix ([Link](https://doi.org/10.1091/mbc.11.4.1457)). This is critical for processes like neuronal migration and axon guidance during '[developmental biology](/details-cell/R-HSA-1266738)'. The gene product is an integral component of the '[plasma membrane](/details-cell/GO0005886)' and is specifically enriched in synaptic structures, including the '[glutamatergic synapse](/details-cell/GO0098978)' and the '[presynaptic membrane](/details-cell/GO0042734)'. Its involvement in '[Lgi-adam interactions](/details-cell/R-HSA-5682910)' is particularly noteworthy, as this pathway is crucial for synaptic transmission and has been linked to forms of epilepsy. While its '[metalloendopeptidase activity](/details-cell/GO0004222)' is a defining feature, the specific substrates of [ADAM23](/details-gene/8745) in the nervous system are not fully elucidated but are presumed to be involved in modulating the synaptic environment through '[proteolysis](/details-cell/GO0006508)'. Studies have also identified multiple isoforms of the gene that are differentially expressed during brain development ([Link](https://doi.org/10.1016/j.gene.2003.10.012)). ## Research Directions The specific and high-level expression of [ADAM23](/details-gene/8745) in distinct neuronal populations, coupled with its dual functions in adhesion and proteolysis, points to several avenues for future research. **Proposed Hypotheses:** 1. Given its high significance in multiple subtypes of cortical interneurons and its role in '[cell adhesion](/details-cell/GO0007155)', [ADAM23](/details-gene/8745) may be essential for the tangential migration and subsequent laminar integration of these neurons during corticogenesis. Its dysregulation could lead to defects in inhibitory circuit formation. 2. Based on its localization to the '[presynaptic membrane](/details-cell/GO0042734)' and its '[metalloendopeptidase activity](/details-cell/GO0004222)', [ADAM23](/details-gene/8745) likely functions as a key regulator of synaptic plasticity by cleaving specific cell surface or extracellular matrix proteins, thereby altering synaptic strength and structure. **Experimental Approach:** To test the hypothesis that [ADAM23](/details-gene/8745) modulates synaptic plasticity (Hypothesis 2), a conditional knockout (cKO) mouse model could be generated to specifically delete the gene in excitatory neurons of the hippocampus (e.g., using a CamKII-Cre driver). Electrophysiological recordings from hippocampal slices of these cKO mice could then be performed to assess for deficits in long-term potentiation (LTP) or long-term depression (LTD). Complementary proteomic analysis of synaptosome preparations from wild-type versus cKO mice could identify candidate protein substrates cleaved by [ADAM23](/details-gene/8745). **Therapeutic Potential:** As a cell-surface protein with enzymatic activity, [ADAM23](/details-gene/8745) presents a potentially druggable target. However, its widespread and critical role in the healthy adult brain suggests that systemic inhibition could lead to significant neurological side effects. Its therapeutic potential may be more relevant in pathologies where it is aberrantly expressed, such as in certain brain tumors (e.g., glioblastomas) where cell adhesion and proteolysis are dysregulated. In such a context, targeted delivery of a small molecule inhibitor or an antibody-drug conjugate designed to neutralize its function could represent a viable therapeutic strategy.
