Protein attributes
| Sequence length | 1798 AA. |
| Sequence status | Complete. |
| Sequence processing | The displayed sequence is not processed. |
| Protein existence | Evidence at protein level. |
General annotation (Comments)
| Function | Appears to link the dystrophin/utrophin network with microtubule filaments via the syntrophins. Phosphorylation of DMD or UTRN may modulate their affinities for associated proteins. Functions in a multi-protein complex in spermatid maturation. Regulates lipopolysaccharide-induced IL-12 synthesis in macrophages by forming a complex with TRAF6, resulting in the inhibition of TRAF6 NF-kappa-B activation By similarity. |
| Catalytic activity | ATP + a protein = ADP + a phosphoprotein. |
| Cofactor | Magnesium By similarity. |
| Subcellular location | Cytoplasm › cytoskeleton. Cell membrane; Peripheral membrane protein; Cytoplasmic sidePotential. Note= Recruited to the sub-membranous area on interaction with PC-LKC. |
| Tissue specificity | Abundant in the testis. |
| Post-translational modification | Phosphorylated and ubiquitinated. N-terminal ubiquitination leads to degradation of MAST2 by proteasome-mediated proteolysis. N-terminal phosphorylation appears to be a prerequisite for ubiquitination By similarity. |
| Sequence similarities | Belongs to the protein kinase superfamily. AGC Ser/Thr protein kinase family. Contains 1 AGC-kinase C-terminal domain. Contains 1 PDZ (DHR) domain. Contains 1 protein kinase domain. |
| Sequence caution | AAH15816.2 sequence differs from that shown. Reason: Frameshift at positions 1114 and 1387. BAB40778.1 sequence differs from that shown. Reason: Frameshift at position 1688. CAH73245.1 sequence differs from that shown. Reason: Erroneous gene model prediction. CAI16563.1 sequence differs from that shown. Reason: Erroneous gene model prediction. CAI21706.1 sequence differs from that shown. Reason: Erroneous gene model prediction. |
