PSD, which called EFA6A, is 63% identical to EFA6B (PSD4) and contains a Sec7 domain adjacent to a PH domain, followed by a C-terminal coiled-coil motif. This gene is mapped to chromosome 10q24. And it 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.
