anti- MARK4 antibody

Serine/threonine-protein kinase(PubMed:15009667, PubMed:14594945, PubMed:23666762, PubMed:23184942). Phosphorylates the microtubule-associated protein MAPT(PubMed:14594945, PubMed:23666762). Also phosphorylates the microtubule-associated proteins MAP2 and MAP4(PubMed:14594945). Involved in regulation of the microtubule network, causing reorganization of microtubules into bundles(PubMed:14594945, PubMed:25123532). Required for the initiation of axoneme extension during cilium assembly(PubMed:23400999). Regulates the centrosomal location of ODF2 and phosphorylates ODF2 in vitro(PubMed:23400999). Plays a role in cell cycle progression, specifically in the G1/S checkpoint(PubMed:25123532). Reduces neuronal cell survival(PubMed:15009667). Plays a role in energy homeostasis by regulating satiety and metabolic rate(By similarity). Promotes adipogenesis by activating JNK1 and inhibiting the p38MAPK pathway, and triggers apoptosis by activating the JNK1 pathway(By similarity). Phosphorylates mTORC1 complex member RPTOR and acts as a negative regulator of the mTORC1 complex, probably due to disruption of the interaction between phosphorylated RPTOR and the RRAGA/RRAGC heterodimer which is required for mTORC1 activation(PubMed:23184942).

Recombinant Human MARK4

MARK4 Serine/Threonine Protein Kinase (MARK4) Antibody

MARK4 contains an N-terminal serine/threonine kinase domain, a central ubiquitin-associated domain, and a C-terminal KA1-associated kinase domain. RT-PCR analysis detects upregulated expression of the gene for MARK4 in nearly all clinical hepatocellular carcinoma cells. Northern blot analysis reveals ubiquitous expression of a 3.6-kb transcript, with highest expression in testis. Immunofluorescence microscopy demonstrates homogeneous cytoplasmic expression. Colony-forming assays show that MARK4 antisense reduces the growth of SNU475 cells. It has been suggested that MARK4 provides a growth advantage to cells.
