Post Translational Modifications | N- and O-glycosylated. May be proteolytically processed during the epididymal transit of spermatozoa. Ubiquitinated, leading to its degradation. Deubiquitinated by USP16, promoting its stability. |
Function | Microtubule inner protein (MIP) part of the dynein-decorated doublet microtubules (DMTs) in cilia and flagellar axoneme. Forms filamentous polymers in the walls of ciliary and flagellar microtubules. Required for normal sperm mobility. |
Protein Name | Tektin-3 |
