Tektins are evolutionarily conserved filament-forming proteins localized in flagella and cilia that have been reported to be involved in the stability and structural complexity of axonemal microtubules.
In some of these species, the concentrations of mercury that were effective on intact sperm had no effect on the axonemal apparatus of demembranated spermatozoa (Cosson et al., 1999) or on glycerol-activated sperm (Takei et al., 2015), suggesting that the motile apparatus is not directly compromised by low concentrations of Hg[Cl.sub.2].
These included, for example, vitelline envelope sperm for lysin receptor (VERL), hydroxysteriod dehydrogenase-like protein, gonadotrophl inducible ovarian transcription factor 1 (GIOT1), axonemal protein p66.0 (Ha-Axp66.0), tektinA1 (Ha-TekA1), vitellogenhl 1 (HaVTG1), fertilization protein (Ha-FP), and small androgen receptor-interacting protein (SARIP).
Another hypothesis involves a series of interrelated events resulting in a decrease in axonemal protein phosphorylation and sperm immobilization, both of which are associated with a reduction in membrane fluidity that is necessary for sperm-oocyte fusion (44).
However, sperms of fish caught from the polluted sites showed variable deformations including: changes in head morphology, incomplete chromatin condensation, malformed middle piece, altered axonemal structure, wavy and sometimes ruptured plasma membrane, head-to-head and head-to-tail sperm agglutinations.
Only the anterior part is more or less lens-shaped, containing the axonemal basis and the implantation fossa (Fig.
Ultrastructural analysis of both sim/sec [F.sub.1] hybrids revealed similarities in axonemal development; however, differences in microtubule development were also observed between the two hybrids, with D.
Spermatozoa membrane of bulls and rams contains high PUFA resulting in more susceptible to ROS that leads to declined sperm mobility, viability and sperm-oocyte fusion due to a reduction in axonemal protein phosphorylation [107].
As shown in Table 3, TSG101 and ZNRD1 are coexpressed with 25981 (DNAH1; dynein axonemal heavy chain 1) and 55567 (DNAH3; dynein axonemal heavy chain 3) in the Huntington's disease pathways.
