一般描述

鱼精蛋白是一种富含半胱氨酸和精氨酸的蛋白质。它具有多个磷酸化位点。鲑鱼含有大约15个编码鱼精蛋白的基因。它位于精子头部。

应用

鲑鱼中的鱼精蛋白已被用于在经肝素预处理的狗的样品中,以避免体外AT复合物的形成。它还已被用于研究外部电势对多种蛋白质在金属表面吸附的影响。

生化/生理作用

以固体脂质纳米粒 (SLN) 形式存在的鱼精蛋白促进质粒 DNA 转染的效率和细胞毒性低于由 Esterquat-1 组成的类似 SLN。
在动植物中,精蛋白被发现在生精过程中可置换DNA中的组蛋白在心脏手术、透析和许多其他临床操作中,鱼精蛋白可用作肝素中和剂。

DNA looping plays an important role in cells in both regulating and protecting the genome. Often, studies of looping focus on looping by prokaryotic transcription factors like lac repressor or by structural maintenance of chromosomes proteins such as condensin. Here

Histone H1 preferentially binds and aggregates scaffold-associated regions (SARs) via the numerous homopolymeric oligo(dA).oligo(dT) tracts present within these sequences. Here we show that the mammalian somatic subtypes H1a,b,c,d,e and H1 degrees and the male germline-specific subtype H1t, all preferentially bind
