CATEGORY

transport channel

SUBCELLULAR LOCALIZATION	intracellular
	intracellular,cytoplasm,organelle,membrane
	intracellular,cytoplasm,organelle,endoplasmic reticulum
	intracellular,cytoplasm,cytosolic,granule
text	present in finely granular structures and was located exclusively in the ER

basic FUNCTION	playing a crutial role in the insertion of secretory and membrane polypeptides into the ER
	required for assembly of membrane and secretory proteins
	SEC61A1 complexes that are present in the ER membrane of nucleated cells form calcium leak channels that may play a crucial role in calcium homeostasis
	heterotrimeric SEC61A1 complex, which forms a dynamic polypeptide-conducting channel in the ER membrane
	role for SEC61A1 in the formation of the minimal filtration unit of the kidney, the nephron
	LONRF1, CDK1, RPL18, GNB2L1 (RACK1), RPL30, and SEC61A1 are crucial components in the diagnosis and treatment of Prostate carcinoma

CELLULAR PROCESS

protein, post translation, targeting

PHYSIOLOGICAL PROCESS

cellular trafficking transport

text	protein transport

PATHWAY

metabolism

signaling

a component

gamma forming a transmembrane channel (Sec61 complex) where proteins are translocated across and integrated into the ER membrane

INTERACTION

DNA

RNA

small molecule

protein	HSPA5 limits ER Ca(2+) leakage through the SEC61A1 complex by binding to the ER lumenal loop 7 of Sec61A1 in the vicinity of tyrosine 344
	DNAJB11 associates with a large complex including SEC61A1
	co-chaperone-controlled gating of the SEC61A1 channel by HSPA5 is particularly important for cells, which are highly active in protein secretion, and breakdown of this regulatory mechanism can cause apoptosis and disease
	PEX3 inserts co-translationally into the mammalian ER via the SEC61A1 translocon

cell & other

tightly binding to membrane-bound ribosomes, either directly or through adapter proteins
