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-600. Isoform J is phosphorylated on Ser-631. Ref.7 Ref.8 Ref.9 Ref.10 Ref.11

Sequence similarities

Belongs to the kinesin light chain family.

Contains 6 TPR repeats.

Caution

It is uncertain whether Met-1 or Met-5 is the initiator.
