Relative content of proteins and components of the sperm tail axoneme. (A) alphaTub84, alpha-tubulin84D, and alpha-tubulin84B (50 kDa), components of the tubulin heterodimer; (B) betaTub56D, beta-tubulin (50 kDa), component of the tubulin heterodimer; (C) Cct4 (CG5525), chaperonin containing Tcp1 subunit 4-delta (56 kDa), participates in the assembly of tubulin heterodimers. Typical western blots for each protein are performed under the according histogram.
