General annotation (Comments)
| Function | Involved in myofibrillogenesis. Seems to be involved in assembly of myosin into sarcomeric A bands in striated muscle By similarity. UniProtKB Q5VST9 |
| Catalytic activity | ATP + a protein = ADP + a phosphoprotein. UniProtKB P28523 |
| Cofactor | Magnesium By similarity. UniProtKB P28523 |
| Sequence similarities | Belongs to the protein kinase superfamily. CAMK Ser/Thr protein kinase family. Contains 1 DH (DBL-homology) domain. Contains 3 fibronectin type-III domains. Contains 55 Ig-like (immunoglobulin-like) domains. Contains 1 IQ domain. Contains 1 PH domain. Contains 2 protein kinase domains. Contains 1 SH3 domain. |
| Sequence caution | The sequence CAM24490.2 differs from that shown. Reason: Erroneous gene model prediction. The sequence CAM24491.3 differs from that shown. Reason: Erroneous gene model prediction. The sequence CAQ51661.2 differs from that shown. Reason: Erroneous gene model prediction. |
Ontologies
Alternative products
| This entry describes 3 isoforms produced by alternative splicing. [Align] [Select] | ||||||
| Isoform 1 Ref.2 (identifier: A2AAJ9-1) This isoform has been chosen as the 'canonical' sequence. All positional information in this entry refers to it. This is also the sequence that appears in the downloadable versions of the entry. | ||||||
| Isoform 2 Ref.3 (identifier: A2AAJ9-2) The sequence of this isoform differs from the canonical sequence as follows: 7161-7167: VCSHDTS → ERRPSPP 7168-8891: Missing. | ||||||
| Note: Lacks the kinase domain. No experimental confirmation available. | ||||||
| Isoform 3 Ref.1 Ref.2 (identifier: A2AAJ9-3) The sequence of this isoform differs from the canonical sequence as follows: 1-7306: Missing. 8384-8389: Missing. |
