Genes affected
HERC1 (HGNC:4867): (HECT and RLD domain containing E3 ubiquitin protein ligase family member 1) This gen encodes a member of the HERC protein family. This protein stimulates guanine nucleotide exchange on ARF1 and Rab proteins. This protein may be involved in membrane transport processes. [provided by RefSeq, Mar 2012]
