精子蛋白可能在生殖中起着关键作用,但在许多非模型动物中,它们的身份尚不清楚。报道了单环刺鳅(Urechis unicinctus)精子蛋白的147个蛋白质组。单环刺鳅是环节动物门的第一个精子蛋白质组。Echiuran精子蛋白质组可以分为不同的功能组:能量代谢(31%),蛋白质合成和降解(18%),精子发生和精子运动(12%),信号通路(11%),离子通道和转运蛋白(6%),细胞骨架(4%),免疫和应激反应(3%)和受精(1%)。这些结果将有助于研究echiurans的受精机制,以及比较研究的繁殖和进化的lophotrochozoans。数据可通过ProteomeXchange获得,标识符为PXD 009176。
Sperm proteins presumably play critical roles in reproduction, but in many non‐model animals their identities are unknown. A total of 147 sperm proteins from the echiuran worm Urechis unicinctus, the first sperm proteome in the phylum Annelida, are reported. The echiuran sperm proteome can be classified into diverse functional groups: energy metabolism (31%), protein synthesis and degradation (18%), spermatogenesis and sperm motility (12%), signal pathway (11%), ion channel and transport proteins (6%), cytoskeleton (4%), immunity and stress responses (3%), and fertilization (1%). These results will facilitate studies of mechanisms of fertilization in echiurans, as well as comparative studies of reproduction and evolution across lophotrochozoans. Data are available via ProteomeXchange with identifier PXD009176.
