ALKBH4是2-氧戊二酸和Fe2+依赖的羟基酶家族中的一种AlkB同系物,先前已被证明调节肌动蛋白中单甲基化赖氨酸-84的水平,从而间接影响非肌肉肌球蛋白II结合肌动蛋白细丝的能力。ALKBH4调节胞质分裂和细胞运动等基本过程,其缺失在植入前胚胎早期是致命的。这项研究的目的是利用可诱导的AlkbH4基因敲除小鼠,在生理学背景下研究AlkBH4缺乏的影响。在此,我们报道了ALKBH4在精母细胞减数分裂前期的发育中是必不可少的,并且ALKBH4的缺失导致联会复合体的建立不足。我们还发现ALKBH4定位于支持细胞、精原细胞和初级精母细胞的核仁结构中。
ALKBH4, an AlkB homologue in the 2-oxoglutarate and Fe2+ dependent hydroxylase family, has previously been shown to regulate the level of monomethylated lysine-84 in actin and thereby indirectly influences the ability of non-muscular myosin II to bind actin filaments. ALKBH4 modulates fundamental processes including cytokinesis and cell motility, and its depletion is lethal during early preimplantation embryo stage. The aim of this study was to investigate the effect of ALKBH4 deficiency in a physiological context, using inducible Alkbh4 knockout mice. Here, we report that ALKBH4 is essential for the development of spermatocytes during the prophase of meiosis, and that ALKBH4 depletion leads to insufficient establishment of the synaptonemal complex. We also show that ALKBH4 is localized in nucleolar structures of Sertoli cells, spermatogonia and primary spermatocytes.
