20250201IID00877Protein salvador homolog 145 kDa WW domain proteinHomo sapiens383Q9H4B6A8K4B8D3DSB6Q6IA58Q9H949Q9HAK9Regulator of STK3/MST2 and STK4/MST1 in the Hippo signaling pathway which plays a pivotal role in organ size control and tumor suppression by restricting proliferation and promoting apoptosis. The core of this pathway is composed of a kinase cascade wherein STK3/MST2 and STK4/MST1, in complex with its regulatory protein SAV1, phosphorylates and activates LATS1/2 in complex with its regulatory protein MOB1, which in turn phosphorylates and inactivates YAP1 oncoprotein and WWTR1/TAZ. Phosphorylation of YAP1 by LATS1/2 inhibits its translocation into the nucleus to regulate cellular genes important for cell proliferation, cell death, and cell migration. SAV1 is required for STK3/MST2 and STK4/MST1 activation and promotes cell-cycle exit and terminal differentiation in developing epithelial tissues. Plays a role in centrosome disjunction by regulating the localization of NEK2 to centrosomes, and its ability to phosphorylate CROCC and CEP250. In conjunction with STK3/MST2, activates the transcriptional activity of ESR1 through the modulation of its phosphorylation.Cytoplasm.SL-0086unkown00Phosphoserine9494Phosphoserine136136Phosphothreonine210210SAV1Protein salvador homolog 1MLSRKKTKNEVSKPAEVQGKYVKKETSPLLRNLMPSFIRHGPTIPRRTDICLPDSSPNAFSTSGDVVSRNQSFLRTPIQRTPHEIMRRESNRLSAPSYLARSLADVPREYGSSQSFVTEVSFAVENGDSGSRYYYSDNFFDGQRKRPLGDRAHEDYRYYEYNHDLFQRMPQNQGRHASGIGRVAATSLGNLTNHGSEDLPLPPGWSVDWTMRGRKYYIDHNTNTTHWSHPLEREGLPPGWERVESSEFGTYYVDHTNKKAQYRHPCAPSVPRYDQPPPVTYQPQQTERNQSLLVPANPYHTAEIPDWLQVYARAPVKYDHILKWELFQLADLDTYQGMLKLLFMKELEQIVKMYEAYRQALLTELENRKQRQQWYAQQHGKNF16ao5B291376order126ao5B377383disorder116ao5X-RAY293K29063833S.J.BAE,L.NI,A.OSINSKI,D.R.TOMCHICK,C.A.BRAUTIGAM,X.LUOSAV1 PROMOTES HIPPO KINASE ACTIVATION THROUGH ANTAGONIZING THE PP2A PHOSPHATASE STRIPAK.2017ELIFE6x-ray6ao5B291383100137738316ao5_12605Hetero dimer6ao5BQ9H4B6IID008776ao5AQ13188IID007216ao5B-6ao5AQ9H8S9-1MOB1A/LATS1pMob1-Lats1 complex200-229,239-265,292-3791-199,230-238,266-291,380-383199-273,304-3711-198,274-303,372-3831-44,125-144,154-159,281-303,372-383275-286
