Acts like a sheddase by mediating the proteolytic release and secretion of active site- containing ectodomains of glycan-modifiying glycosidase and glycosyltransferase enzymes such as MGAT5, B4GAT1 and B4GALT1 (PubMed:25354954, PubMed:25827571). Catalyzes the intramembrane cleavage of the envelope glycoprotein gp130 and/or the leader peptide gp18LP of the simian foamy virus independent of prior ectodomain shedding by furin or furin-like proprotein convertase (PC)-mediated cleavage proteolysis (PubMed:23132852). May also have the ability to serve as a shedding protease for subsequent intramembrane proteolysis by SPPL2A and SPPL2B of the envelope glycoprotein gp130 (PubMed:23132852). Plays a role in the regulation of cellular glycosylation processes (PubMed:25354954). Required to link T-cell antigen receptor (TCR) and calcineurin- NFAT signaling cascades in lymphocytes by promoting the association of STIM1 and ORAI1 during store-operated calcium entry (SOCE) in a protease-independent manner (PubMed:25384971). {ECO:0000269|PubMed:16873890, ECO:0000269|PubMed:23132852, ECO:0000269|PubMed:25354954, ECO:0000269|PubMed:25384971, ECO:0000269|PubMed:25827571}. |Peptidase A22B| |integral component of cytoplasmic side of endoplasmic reticulum membrane| |aspartic endopeptidase activity, intramembrane cleaving| |signal peptide processing| |positive regulation of calcineurin-mediated signaling| |positive regulation of calcineurin-NFAT signaling cascade| |Golgi-associated vesicle membrane| |membrane protein ectodomain proteolysis| |integral component of lumenal side of endoplasmic reticulum membrane| |regulation of calcineurin-mediated signaling| |regulation of calcineurin-NFAT signaling cascade| |membrane protein proteolysis| |positive regulation of calcium-mediated signaling| |positive regulation of protein dephosphorylation| |positive regulation of dephosphorylation| |rough endoplasmic reticulum| |endoplasmic reticulum-Golgi intermediate compartment membrane| |positive regulation of protein binding| |regulation of calcium-mediated signaling| |regulation of protein dephosphorylation| |protein processing| |T cell receptor signaling pathway| |positive regulation of binding| |regulation of dephosphorylation| |regulation of protein binding| |protein maturation| |positive regulation of cytosolic calcium ion concentration| |antigen receptor-mediated signaling pathway| |regulation of cytosolic calcium ion concentration| |regulation of binding| |cellular calcium ion homeostasis| |calcium ion homeostasis| |immune response-activating cell surface receptor signaling pathway| |cellular divalent inorganic cation homeostasis| |immune response-regulating cell surface receptor signaling pathway| |divalent inorganic cation homeostasis| |peptide metabolic process| |cellular metal ion homeostasis| |immune response-activating signal transduction| |immune response-regulating signaling pathway| |metal ion homeostasis| |activation of immune response| |cellular cation homeostasis| |cellular ion homeostasis| |intracellular membrane-bounded organelle| |cation homeostasis| |inorganic ion homeostasis| |cellular chemical homeostasis| |ion homeostasis| |cellular amide metabolic process| |positive regulation of immune response| |protein homodimerization activity| |cellular homeostasis| |Golgi apparatus| |positive regulation of intracellular signal transduction| |chemical homeostasis| |positive regulation of phosphate metabolic process| |positive regulation of phosphorus metabolic process| |regulation of immune response| |positive regulation of immune system process| |positive regulation of protein modification process| |proteolysis| |positive regulation of cellular protein metabolic process| |homeostatic process| |regulation of immune system process| |positive regulation of signal transduction| |positive regulation of protein metabolic process| |positive regulation of molecular function| |regulation of phosphate metabolic process| |regulation of phosphorus metabolic process| |positive regulation of cell communication| |positive regulation of signaling| |regulation of intracellular signal transduction| |regulation of protein modification process| |membrane| |gene expression| \\ === CRISPR Data === No hits were found. ^Gene^Correlation^ |[[:human genes:p:prim1|PRIM1]]|0.559| Global Fraction of Cell Lines Where Essential: 0/739 ^Tissue^Fraction Of Cell Lines Where Essential^ |1290807.0|0/1| |909776.0|0/1| |bile duct|0/28| |blood|0/28| |bone|0/26| |breast|0/33| |central nervous system|0/56| |cervix|0/4| |colorectal|0/17| |esophagus|0/13| |fibroblast|0/1| |gastric|0/16| |kidney|0/21| |liver|0/20| |lung|0/75| |lymphocyte|0/16| |ovary|0/26| |pancreas|0/24| |peripheral nervous system|0/16| |plasma cell|0/15| |prostate|0/1| |skin|0/24| |soft tissue|0/9| |thyroid|0/2| |upper aerodigestive|0/22| |urinary tract|0/29| |uterus|0/5| == Essentiality in NALM6 == * **Essentiality Rank**: 16531 * **Expression level (log2 read counts)**: 5.7 {{:chemogenomics:nalm6 dist.png?nolink |}}
