Gene Summary:
- DBD Genes Classification
- ASTN2 is an Emerging candidate gene classified as Tier 4. Tier 4 genes no de novo pathogenic loss-of-function variants.
- Gene Function
- Mediates recycling of the neuronal cell adhesion molecule ASTN1 to the anterior pole of the cell membrane in migrating neurons. Promotes ASTN1 internalization and intracellular transport of endocytosed ASTN1 (By similarity). Selectively binds inositol-4,5- bisphosphate, inositol-3,4,5-trisphosphate and inositol-1,3,4,5- tetrakisphosphate, suggesting it is recruited to membranes that contain lipids with a phosphoinositide headgroup (Ref.6). {ECO:0000250|UniProtKB:Q80Z10, ECO:0000269|Ref.6}.
