RAB3GAP1 RAB3 GTPase activating protein catalytic subunit 1 [Homo sapiens (human)] - Gene

Summary

Official Symbol: RAB3GAP1provided by HGNC
Official Full Name: RAB3 GTPase activating protein catalytic subunit 1provided by HGNC
Primary source: HGNC:HGNC:17063

Gene type: protein coding
RefSeq status: REVIEWED
Organism: Homo sapiens
Lineage: Eukaryota; Metazoa; Chordata; Craniata; Vertebrata; Euteleostomi; Mammalia; Eutheria; Euarchontoglires; Primates; Haplorrhini; Catarrhini; Hominidae; Homo
Also known as: P130; MARTS2; WARBM1; RAB3GAP; RAB3GAP130
Summary: This gene encodes the catalytic subunit of a Rab GTPase activating protein. The encoded protein forms a heterodimer with a non-catalytic subunit to specifically regulate the activity of members of the Rab3 subfamily of small G proteins. This protein mediates the hydrolysis of GTP bound Rab3 to the GDP bound form. Mutations in this gene are associated with Warburg micro syndrome. Alternate splicing results in multiple transcript variants.[provided by RefSeq, Feb 2010]
Expression: Ubiquitous expression in brain (RPKM 16.8), thyroid (RPKM 15.9) and 25 other tissues See more

RefSeqs maintained independently of Annotated Genomes

These reference sequences exist independently of genome builds. Explain

These reference sequences are curated independently of the genome annotation cycle, so their versions may not match the RefSeq versions in the current genome build. Identify version mismatches by comparing the version of the RefSeq in this section to the one reported in Genomic regions, transcripts, and products above.
