Changes in calmodulin level and cAMP-dependent protein kinase activity during epididymal maturation of ram spermatozoa.
Calmodulin concentration and cAMP-dependent protein kinase activity were simultaneously determined on ram spermatozoa collected by cannulation of successive segments of the epididymal tubule. Epididymal transit was characterized on one hand by an overall decrease in the calmodulin level and on the other by a dramatic rise in the cAMP-dependent protein kinase activity. In contrast to the calmodu...
متن کاملLocalization of calmodulin in rat cerebellum by immunoelectron microscopy
Calmodulin, a multifunctional Ca(++)-binding protein, is present in all eucaryotic cells. We have investigated the distribution of this protein in the rat cerebellum by immunoelectron microscopy using a Fab-peroxidase conjugate technique. In Purkinje and granular cell bodies, calmodulin reaction product was found localized both on free ribosomes and on those attached to rough endoplasmic reticu...
متن کاملLeptin Receptor in Ram Epididymal Spermatozoa
This experiment was designed to investigate leptin receptors (Ob-R and Ob-Rb) mRNA in ram epididymal spermatozoa by RT-PCR. Ten testes were obtained from abattoir and epididymal spermatozoa recovery was performed. To purify spermatozoa, motile sperm were isolated by the swim-up procedure. Total RNA was isolated from epididymal spermatozoa and placental cotyledon, as a positive control, and then...
متن کاملNonpathological Extracellular Amyloid Is Present during Normal Epididymal Sperm Maturation
Amyloids are aggregated proteins characterized by a specific cross-β-sheet structure and are typically associated with neurodegenerative diseases including Alzheimer's disease. Recently, however, several nonpathological amyloids have been found in intracellular organelles of normal mammalian tissues suggesting that amyloid may also carry out biological functions. We previously have shown that t...
متن کاملProteomic changes in mammalian spermatozoa during epididymal maturation.
Epididymal maturation is associated with the activation of a cAMP-induced tyrosine phosphorylation cascade, which is ultimately associated with the expression of capacitation-dependent sperm functions, such as hyperactivated movement and acrosomal exocytosis. As spermatozoa progress through the epididymis they first acquire the capacity to phosphorylate tyrosine on targets on the principal piec...
