About DENND5A

Cytogenetic location: 11p15.4 Genomic coordinates (GRCh38): 11:9,138,825-9,265,350 (from NCBI)

This gene has 40 transcripts (splice variants), 207 orthologues, 10 paralogues and is associated with 2 phenotypes. Ubiquitous expression in brain (RPKM 36.4), heart (RPKM 21.0) and 25 other tissues.

Summary

This gene encodes a DENN-domain-containing protein that functions as a RAB-activating guanine nucleotide exchange factor (GEF). This protein catalyzes the conversion of GDP to GTP and thereby converts inactive GDP-bound Rab proteins into their active GTP-bound form. The encoded protein is recruited by RAB6 onto Golgi membranes and is therefore referred to as RAB6-interacting protein 1. This protein binds with RAB39 as well. Alternative splicing results in multiple transcript variants encoding distinct isoforms. Mutations in this gene are associated with early infantile epileptic encephalopathy-49.
