MAP/microtubule affinity-regulating kinase 3 (MARK3)

The protein contains 753 amino acids for an estimated molecular weight of 84489 Da.

 

Serine/threonine-protein kinase (PubMed:23666762). Involved in the specific phosphorylation of microtubule-associated proteins for MAP2 and MAP4. Phosphorylates the microtubule-associated protein MAPT/TAU (PubMed:23666762). Phosphorylates CDC25C on 'Ser-216'. Regulates localization and activity of some histone deacetylases by mediating phosphorylation of HDAC7, promoting subsequent interaction between HDAC7 and 14-3-3 and export from the nucleus (PubMed:16980613). Negatively regulates the Hippo signaling pathway and antagonizes the phosphorylation of LATS1. Cooperates with DLG5 to inhibit the kinase activity of STK3/MST2 toward LATS1 (PubMed:28087714).

CLONING

MARK proteins are involved in the specific phosphorylation of microtubule-associated proteins for tau (157140), MAP2 (157130), and MAP4 (157132). MARK3 was originally identified as a marker (KP78) that was induced by treatment with DNA damaging agents, and loss of MARK3 was found with carcinogenesis in the pancreas (Parsa, 1988). MARK3 may be involved in cell cycle regulation, and alterations in the MARK3 gene may lead to carcinogenesis. Peng et al. (1998) cloned a full-length HeLa cell cDNA encoding MARK3, which they called CTAK1. By Northern blot analysis, CTAK1 was expressed as 3.1- and 3.8-kb transcripts in all human tissues examined; an additional 3.0-kb transcript was observed in heart. The predicted 729-amino acid CTAK1 protein belongs to the AMPK (e.g., 602739) subfamily of protein kinases. Members of this subfamily are characterized by a conserved N-terminal kinase domain, a divergent C-terminal region, and a conserved region of about 40 amino acids at their extreme C-termini, which end with an ELKL (glutamate-leucine-lysine-leucine) domain. CTAK1 protein from HeLa cell lysates resolved as a doublet of approximately 78 and 80 kD in Western blot and immunoprecipitation analyses. Indirect immunofluorescence detected CTAK1 in the cytoplasm but not the nucleus of HeLa cells. The authors demonstrated that CTAK1 binds to CDC25C (157680) and phosphorylates CDC25C on serine-216 in vitro and in vivo. Using Western blot analysis, Lennerz et al. (2010) found that Par1a was expressed at variable levels in all mouse tissues examined. Database analysis suggested the presence of 5 Par1a splice variants encoding proteins of 659 to 753 amino acids.

BIOCHEMICAL FEATURES

Muller et al. (2001) showed that KSR1 (601132) translocates from the cytoplasm to the cell surface in response to growth factor treatment and that this process is regulated by CTAK1. CTAK1 constitutively associates with mammalian KSR1 and phosphorylates ser392 to confer 14-3-3 binding and cytoplasmic sequestration of KSR1 in unstimulated cells. In response to signal activation, the phosphorylation state of ser392 is reduced, allowing the KSR1 complex to colocalize with activated RAS and RAF1 (164760) at the plasma membrane, thereby facilitating the phosphorylation reactions required for the activation of MEK and MAPK (see 176872).

MAPPING

Ono et al. (1997) used fluorescence in situ hybridization to map the MARK3 gene to 14q32.3.

ANIMAL MODEL

Lennerz et al. (2010) obtained Par1a -/- mice at less than mendelian ratios. Those that survived were viable and developed normally, but became hypermetabolic and showed reduced body weight, adiposity, and hypofertility compared with wildtype. Par1a -/- mice on a high-fat diet exhibited profound resistance to development of glucose intolerance, weight gain, and hepatic steatosis. Upon short-term starvation, livers of Par1a -/- mice exhibited defects in both glycogen storage and glucose mobilization, with depletion of lipid and glycogen stores, upregulation of glycogen synthase (GYS1; 138570), and activation of autophagy. This phenotype partly overlapped that displayed by Par1b -/- mice. Double knockout of Par1a and Par1b in mice was embryonic lethal. At least 1 allele of either Par1a or Par1b was necessary for viability, but mice expressing only 1 Par1 allele were not healthy, and a high proportion died shortly after birth. ...
