General annotation (Comments)
| Function | Kinesin is a microtubule-associated force-producing protein that may play a role in organelle transport. The light chain may function in coupling of cargo to the heavy chain or in the modulation of its ATPase activity. |
| Subunit structure | Oligomeric complex composed of two heavy chains and two light chains. Interacts with SPAG9 By similarity. |
| Tissue specificity | Found in a variety of tissues. Mostly abundant in brain and spine. |
| Post-translational modification | Isoform I is phosphorylated on Ser-596. Isoform J is phosphorylated on Ser-627. |
| Sequence similarities | Belongs to the kinesin light chain family. Contains 6 TPR repeats. |
