text	integral membrane protein located in the rough ER

basic FUNCTION	performing post-translational protein translocation into the ER (Sec61-Sec62-Sec63 complex)
	performing the backward transport of ER proteins that are subject to the ubiquitin-proteasome-dependent degradation pathway (Sec61-Sec62-Sec63 complex)
	acting as an endoplasmic reticulum receptor
	key component of the protein translocation machinery in the mammalian endoplasmic reticulum (ER), and involved in the post-translation processing of secretory proteins
	possible role for SEC63 in decidualization
	PRKCSH and SEC63 function in protein translocation and quality control pathways in the endoplasmic reticulum

CELLULAR PROCESS

protein, post translation, targeting

PHYSIOLOGICAL PROCESS

cellular trafficking transport

text	protein-membrane targeting

PATHWAY

metabolism

signaling

a component

component of the transmembrane complex mediating posttranslational translocation of nescent peptides across the ER

INTERACTION

DNA

RNA

small molecule

protein	binding with SEC62 to ribosome-free SEC61 complex
	binding to heat shock protein
	binding to unfolded protein
	NXN is an interaction partner of SEC63
	is linked to the Wnt signaling pathways and this interaction may be the reason why mutations in SEC63 can lead to PCLD
