Palmitoylated proteins in bovine ovarian cumulus-oocyte complexes


ABSTRACT: The palmitoyl-proteome of bovine cumulus-oocyte complexes (COCs) cells was investigated by combining acyl-biotin exchange chemistry and quantitative mass spectrometry analysis.

Protein palmitoylation is a reversible post-translational modification by fatty acids (FA), mainly a palmitate (C16:0). Palmitoylation allows protein shuttling between the plasma membrane and cytosol to regulate protein stability, sorting and signaling activity and its deficiency leads to diseases. We aimed to characterize the palmitoyl-proteome of ovarian follicular cells and molecular machinery regulating protein palmitoylation within the follicle. For the first time, 84 palmitoylated proteins  ...[more]
