PHYSICAL PROPERTIES

STRUCTURE

motifs/domains	nine tetratricopeptide-like repeats (TPRs) poised to interact with other SRP or ribosomal proteins were predicted in the N-terminal region
	a minimal region capable of forming a stable complex with an SRP RNA fragment encompassed AAs 545 to 585 of the full-length SRP72 and contained a lysine-rich cluster (KKKKKKKKGK) at postions 552 to 561 as well as a conserved Pfam motif
	a C terminal domain of interaction with SRP68

	intracellular,cytoplasm,cytosolic,ribosome

basic FUNCTION	playing a crucial role in targeting secretory proteins to rough endoplasmic reticulum membrane
	participating in the elongation arrest function
	implicated in binding to the SRP receptor and promoting the directional translocation of newly translated proteins bearing a signal sequence into the lumen of the ER
	has at least two functions that are individually redundant and the conformation of the complex is critical for efficient completion of its biogenesis
	component of the signal recognition particle (SRP), which is responsible for arresting translation of nascent proteins that are destined for the cell membrane or extracellular secretion and transferring them to the endoplasmic reticulum (ER) for correct trafficking

CELLULAR PROCESS

PHYSIOLOGICAL PROCESS

PATHWAY

metabolism

signaling

a component	S domain made of a unique SRP RNA sequence and SRP9, SRP14, SRP19, SRP54, SRP68, SRP72
	component of a ribonucleoprotein complex
	SRP68 and SRP72 form a heterodimer

INTERACTION

DNA

RNA	binding to 7S RNA in presence of SRP68

small molecule

protein	binding to SRPR
	SRP68-SRP72 interaction remained stable at elevated salt concentrations and engaged approximately 150 amino acids from the N-terminal region of SRP72

cell & other

binding directly to the docking protein in the endoplasmic reticulum membrane

REGULATION

repressed by

inhibitors of the MAPK pathway that down-regulate the expression of SRP72 autoantigen in Jurkat cells

Other

cleaved during apoptosis
