pfam07946: CCDC47 (This model is not part of the current CDD release)
PAT complex subunit CCDC47
This family represents CCDC47 proteins which are a component of the PAT complex, an endoplasmic reticulum (ER)-resident membrane multiprotein complex that facilitates multi-pass membrane proteins insertion into membranes. The PAT complex, formed by CCDC47 and Asterix proteins, acts as an intramembrane chaperone by directly interacting with nascent transmembrane domains (TMDs), releasing its substrates upon correct folding, and is needed for optimal biogenesis of multi-pass membrane proteins. CCDC47 is required to maintain the stability of Asterix. CCDC47 is associated with various membrane-associated processes and is component of a ribosome-associated ER translocon complex involved in multi-pass membrane protein transport into the ER membrane and biogenesis. It is also involved in the regulation of calcium ion homeostasis in the ER, being also required for proper protein degradation via the ERAD (ER-associated degradation) pathway.
