General annotation (Comments)
| Function | 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. Ref.2 |
| Subunit structure | Self-associates. Associates with microtubules and forms a fibrillar structure partially linked to the microtubule network. Interacts via its C-terminus with PLK1. Interacts with ODF1 By similarity. Ref.2 |
| Subcellular location | Cytoplasm › cytoskeleton › centrosome. Cell projection › cilium. Cytoplasm › cytoskeleton › centrosome › centriole. Cytoplasm › cytoskeleton › spindle pole. Note: Localized at the microtubule organizing centers in interphase and spindle poles in mitosis. Localized at the distal/subdistal appendages of mother centrioles. |
| Tissue specificity | Testis-specific (at protein level). Highly expressed in cytoplasm of step 2 round spermatids. Detected in the middle piece and extends to about half the principal piece of the sperm tails. Ref.1 |
| Post-translational modification | Tyrosine phosphorylated By similarity. |
| Sequence similarities | Belongs to the ODF2 family. |
| Sequence caution | The sequence AAC08409.1 differs from that shown. Reason: Erroneous initiation. Translation N-terminally extended. |
