General annotation (Comments)
| Function | Required both for the formation of intercellular bridges during meiosis and for kinetochore-microtubule attachment during mitosis. Intercellular bridges are evolutionarily conserved structures that connect differentiating germ cells and are required for spermatogenesis and male fertility. Acts by promoting the conversion of midbodies into intercellular bridges via its interaction with CEP55: interaction with CEP55 inhibits the interaction between CEP55 and PDCD6IP/ALIX and TSG101, blocking cell abscission and leading to transform midbodies into intercellular bridges. Also plays a role during mitosis: recruited to kinetochores by PLK1 during early mitosis and regulates the maturation of the outer kinetochores and microtubule attachment. Has no protein kinase activity in vitro. Ref.5 Ref.7 Ref.8 Ref.11 |
| Subunit structure | Interacts with KIF23 and RBM44. Interacts with CEP55; inhibiting interaction between CEP55 and PDCD6IP/ALIX and TSG101. Ref.6 Ref.8 Ref.9 |
| Subcellular location | Cytoplasm. Midbody. Chromosome › centromere › kinetochore. Note: Detected in the intercellular bridges that connect male germ cell daughter cells after cell division. Ref.5 Ref.6 Ref.7 Ref.8 Ref.10 Ref.11 |
| Tissue specificity | Detected in testis and spermatogonia. Not detectable in the other tissues tested. Ref.1 Ref.3 Ref.5 |
| Developmental stage | Detected at low levels in developing testis at 5 and 10 days after birth. Highly expressed in testis 15 and 20 days after birth. Highly expressed in pachytene, diplotene and meiotically dividing spermatocytes and in early round spermatids. Ref.3 |
| Domain | The protein kinase domain is predicted to be catalytically inactive. The GPPX3Y motif mediates interaction with CEP55 (Ref.8). |
| Post-translational modification | Phosphorylated on Thr residues by CDK1 during early phases of mitosis, promoting the interaction with PLK1 and recruitment to kinetochores. Phosphorylated on Ser-431 by PLK1 during late prometaphase promotes the rapid depletion from kinetochores and its subsequent degradation by the APC/C complex. Ref.11 |
| Disruption phenotype | Male mice are sterile, due to the absence of intercellular bridges. Intercellular bridges do not form during spermatogenesis, and male mice are sterile. In females, embryonic intercellular bridges are also absent, mice have fewer oocytes, but they are fertile. Ref.5 Ref.7 |
| Miscellaneous | Used as a marker for intercellular bridges (Ref.10). |
| Sequence similarities | Belongs to the protein kinase superfamily. Contains 3 ANK repeats. Contains 1 protein kinase domain. |
| Caution | Ser-370 is present instead of the conserved Asp which is expected to be an active site residue. |
| Sequence caution | The sequence CAI35965.1 differs from that shown. Reason: Erroneous initiation. Translation N-terminally shortened. |
