About AP4S1

Cytogenetic location: 14q12 Genomic coordinates (GRCh38): 14:31,025,106-31,096,450 (from NCBI)

This gene has 13 transcripts (splice variants), 203 orthologues, 6 paralogues and is associated with 3 phenotypes. Ubiquitous expression in brain (RPKM 1.8), testis (RPKM 1.6) and 25 other tissues.

Summary

This gene encodes a member of the adaptor complexes small subunit protein family. These proteins are components of the heterotetrameric adaptor protein complexes, which play important roles in the secretory and endocytic pathways by mediating vesicle formation and sorting of integral membrane proteins. The encoded protein is the small subunit of adaptor protein complex-4, which is associated with both clathrin- and nonclathrin-coated vesicles. Mutations in this gene are associated with spastic quadriplegic cerebral palsy-6. Alternatively spliced transcript variants encoding multiple isoforms have been observed for this gene, and a pseudogene of this gene is located on the long arm of chromosome 6.
