FLASH GENE DNA RNA EXPRESSION PROTEIN DISORDER ANIMAL & CELL MODELS

PROTEIN

PHYSICAL PROPERTIES

STRUCTURE

motifs/domains

C-terminal transmembrane region that mediates post-translational insertion into the membrane of the endoplasmic reticulum (ER)

HOMOLOGY

interspecies	homolog to murine D3Ucla1
	homolog to rattus RAMP4

Homologene

FAMILY

CATEGORY

chaperone/stress

SUBCELLULAR LOCALIZATION	intracellular
	intracellular,cytoplasm,organelle,membrane
	intracellular,cytoplasm,organelle,endoplasmic reticulum
	intracellular,cytoplasm,cytosolic,ribosome
	intracellular,cytoplasm,cytoskeleton,microtubule
text	newly synthesised SERP1 and SEC61B can accumulate in a cytosolic, soluble complex with the ATPase ASNA1 before insertion into ER-derived membranes

basic FUNCTION	stabilizes membrane proteins during stress and facilitates subsequent glycosylation
	tail-anchored (TA) protein, having a functions in the ER stress response
	represents an oxidative stress-associated endoplasmatic reticulum protein with chaperon-like functions
	both VKORC1 and SERP1, might have a synergistic function in eliminating reactive oxygen species generated during the VKOR redox process
	expression of SERP1 strongly inhibits amiloride-sensitive Na(+) transport

CELLULAR PROCESS

protein, post translation

PHYSIOLOGICAL PROCESS

PATHWAY

metabolism

signaling

a component

INTERACTION

DNA

RNA

small molecule

protein	interacting with CANX
	VKORC1 interacting with SERP1, and both might have a synergistic function in eliminating reactive oxygen species generated during the VKOR redox process
	induced during cell stress and interacts with the molecular chaperone calnexin, thus controlling early biogenesis of membrane proteins
	appears to promote expression of CFTR and is a novel cochaperone and regulator of SCNN1A, SCNN1B, SCNN1G expression
