MGI Phenotype FUNCTION: [Summary is not available for the mouse gene. This summary is for the human ortholog.] The signal sequence receptor (SSR) is a glycosylated endoplasmic reticulum (ER) membrane receptor associated with protein translocation across the ER membrane. The SSR consists of 2 subunits, a 34-kD glycoprotein encoded by this gene and a 22-kD glycoprotein. This gene generates several mRNA species as a result of complex alternative polyadenylation. This gene is unusual in that it utilizes arrays of polyA signal sequences that are mostly non-canonical. Multiple transcript variants encoding different isoforms have been found for this gene.

PHENOTYPE: Homozygous mutation of this gene results in neonatal lethality, subcutaneous edema, and cardiac defects, including absence of septation of the proximal part of the outflow tract, double outlet right ventricle, persistent truncus arteriosis, and abnormal development of the endocardial cushion.
