Mypt1 E24 splice variants tune arterial reactivity and could be worthy targets for lowering vascular resistance in disease states.
revealed the presence of two MYPT1 isoforms, full length and variant 2 in human intestinal (Caco-2) epithelial cells and isolated intestinal epithelial cells from mice
phosphorylation of MYPT1 T694, but not T852, mediates force maintenance in bladder smooth muscle.
Constitutive phosphorylation of myosin phosphatase targeting subunit-1 in smooth muscle
Maturation of mesenteric artery smooth muscle involves TRA2beta (show TRA2B ELISA Kits) mediated Mypt1 exon 24 splicing.
The role of MYPT1 in vascular smooth muscle was investigated in adult MYPT1 smooth muscle specific knock-out mice. MYPT1 deletion enhanced phosphorylation of myosin regulatory light chain and contractile force in isolated mesenteric arteries.
MYPT1 is not essential for smooth muscle function in mice but regulates the Ca(2 (show CA2 ELISA Kits)+) sensitivity of force development and contributes to intestinal phasic contractile phenotype.
Tra2beta (show TRA2B ELISA Kits), by regulating the splicing of Mypt1 E23, sets the sensitivity of smooth muscle to cGMP-mediated relaxation.
Organ-specific mechanisms involving MYPT1, M-RIP (show MPRIP ELISA Kits), and CPI-17 (show PPP1R14A ELISA Kits) are critical to regulating basal LC20 (show MYL9 ELISA Kits) phosphorylation in gastrointestinal smooth muscles.
Findings define a new conserved pathway in which sexual development and pregnancy mediate smooth and striated (show NSDHL ELISA Kits) muscle adaptations through SMTNL1 and MYPT1.
BLT2 (show LTB4R2 ELISA Kits) ligation facilitates F-actin assembly with the upregulated phosphorylation of MYPT1.
Lipolysis-stimulated lipoprotein receptors (LSRs) localized to bicellular junctions in association with myosin regulatory light chain 2 (MRLC2 (show MYL12B ELISA Kits)) at low cell densities and to tricellular contacts when myosin phosphatase target subunit 1 (MYPT1) localized to the bicellular regions.
miR (show MLXIP ELISA Kits)-30d and/or its target gene MYPT1 may serve as novel prognostic markers of PCa (show FLVCR1 ELISA Kits). miR (show MLXIP ELISA Kits)-30d promotes tumor angiogenesis of PCa (show FLVCR1 ELISA Kits) through MYPT1/c-JUN (show JUN ELISA Kits)/VEGFA (show VEGFA ELISA Kits) pathway.
Study revealed the presence of two MYPT1 isoforms, full length and variant 2 in human intestinal (Caco-2) epithelial cells and isolated intestinal epithelial cells from mice.
These results indicate that PPP1R12A indeed plays a role in skeletal muscle insulin (show INS ELISA Kits) signaling
the relative expression of LZ+/LZ (show LYZ ELISA Kits)- MYPT1 isoforms, in part, defines the vascular response to NO and NO based vasodilators, and therefore, plays a role in the regulation of vascular tone in both health and disease
Expression of NUAK1 is controlled by cyclin-dependent kinase, PLK1, and the SCFbetaTrCP (Skp, Cullin and F-boxbetaTrCP) E3 ubiquitin ligase complex.
distinct roles of two inhibitory phosphorylation sites of MYPT1
in apoptotic cells, the myosin-binding domain of myosin phosphatase targeting subunit 1 is cleaved by caspase-3, and the cleaved MYPT1 is strongly phosphorylated at Thr-696 and Thr-853, phosphorylation of which is known to inhibit myosin II binding
results suggested that during atherosclerosis progression oxidative stress mediates the downregulation of MYPT1, which may inhibit smooth muscle cell migration and contribute to the aberrant contractility
Myosin phosphatase target subunit 1, which is also called the myosin-binding subunit of myosin phosphatase, is one of the subunits of myosin phosphatase. Myosin phosphatase regulates the interaction of actin and myosin downstream of the guanosine triphosphatase Rho. The small guanosine triphosphatase Rho is implicated in myosin light chain (MLC) phosphorylation, which results in contraction of smooth muscle and interaction of actin and myosin in nonmuscle cells. The guanosine triphosphate (GTP)-bound, active form of RhoA (GTP.RhoA) specifically interacted with the myosin-binding subunit (MBS) of myosin phosphatase, which regulates the extent of phosphorylation of MLC. Rho-associated kinase (Rho-kinase), which is activated by GTP. RhoA, phosphorylated MBS and consequently inactivated myosin phosphatase. Overexpression of RhoA or activated RhoA in NIH 3T3 cells increased phosphorylation of MBS and MLC. Thus, Rho appears to inhibit myosin phosphatase through the action of Rho-kinase. Several transcript variants encoding different isoforms have been found for this gene.
