VPS4A - vacuolar protein sorting 4 homolog A Gene

Also Known as SKD1; SKD2; VPS4; SKD1A; CIMDAG; VPS4-1

Species: Homo sapiens

Gene Type: protein coding

Gene ID: 27183

About VPS4A

Cytogenetic location: 16q22.1 Genomic coordinates (GRCh38): 16:69,311,350-69,326,939 (from NCBI)

This gene has 4 transcripts (splice variants), 213 orthologues, 9 paralogues and is associated with 3 phenotypes. Ubiquitous expression in brain (RPKM 45.1), fat (RPKM 36.4) and 25 other tissues.

Summary

The protein encoded by this gene is a member of the AAA protein family (ATPases associated with diverse cellular activities), and is the homolog of the yeast Vps4 protein. In humans, two paralogs of the yeast protein have been identified. The former share a high degree of aa sequence similarity with each Other, and also with yeast Vps4 and mouse Skd1 proteins. The mouse Skd1 (suppressor of K+ transport defect 1) has been shown to be really an yeast Vps4 ortholog. Functional studies indicate that both human paralogs associate with the endosomal compartments, and are involved in intracellular protein trafficking, similar to Vps4 protein in yeast. The gene encoding this paralog has been mapped to chromosome 16; the gene for the Other resides on chromosome 18. [provided by RefSeq, Jul 2008]
