DESCRIPTION

Also known as ODFP2_HUMAN, ODF2. Seems to be a major component of sperm tail outer dense fibers (ODF). ODFs are filamentous structures located on the outside of the axoneme in the midpiece and principal piece of the mammalian sperm tail and may help to maintain the passive elastic structures and elastic recoil of the sperm tail. May have a modulating influence on sperm motility. Functions as a general scaffold protein that is specifically localized at the distal/subdistal appendages of mother centrioles. Component of the centrosome matrix required for the localization of PLK1 and NIN to the centrosomes. Required for the formation and/or maintenance of normal CETN1 assembly. Self-associates. Associates with microtubules and forms a fibrillar structure partially linked to the microtubule network. Interacts via its C-terminus with PLK1 (PubMed:16966375). Interacts with ODF1 (By similarity). Interacts with MARK4; the interaction is required for localization of ODF2 to centrioles (PubMed:23400999). Interacts with TSSK4 (By similarity). Interacts with AKNA (By similarity). Interacts with QRICH2 (PubMed:30683861). Interacts with CFAP58 (By similarity).
