Summaries for PSD Gene

Entrez Gene Summary for PSD Gene

  • This gene encodes a Plekstrin homology and SEC7 domains-containing protein that functions as a guanine nucleotide exchange factor. The encoded protein regulates signal transduction by activating ADP-ribosylation factor 6. Alternative splicing results in multiple transcript variants. [provided by RefSeq, Aug 2012]

GeneCards Summary for PSD Gene

PSD (Pleckstrin And Sec7 Domain Containing) is a Protein Coding gene. Diseases associated with PSD include Branch Retinal Artery Occlusion. Among its related pathways are Endocytosis.
