Subcellular localization

flagella, nucleus

Functional category

  • Actin & cytoskeleton regulation
  • Reproduction & sperm
  • Protein processing & maturation

Function

The CABYR CR-A antibody localized to the entire length of the principal piece, and, unlike FSCB, CABYR also extended into the end piece (17855365).

Model organism evidence

Mus musculus (2 references)

ASP and ROPN1 are 41% identical in sequence, interact with a variety of AKAPs in a manner similar to PKA, and are expressed in ciliated and flagellated human cells.

CABYR protein gradually migrates into the sperm flagellum and localizes to the FS of the principal piece during steps 15-16.
