CTD small phosphatase-like protein 2 (CTDSPL2, HSPC129) is a putative RNA-polymerase II carboxy-terminal domain (CTD) phosphatase (1) that belongs to a small subfamily of CTD phosphatases (2). The CTD of RNA polymerase II contains multiple Y-S-P-T-S-P-S repeats that are phosphorylated during the transcription cycle (3,4). In general, CTD phosphatases regulate the reversible CTD phosphorylation state of RNA-polymerase II at several stages of RNA synthesis and during post-transcriptional modification (4-6). CTDSPL2 has several structural and functional similarities to other CTD phosphatases, including FCP1, SCP1, DULLARD, and UBLCP1 (1,2).

CTD small phosphatase-like protein 2 (CTDSPL2, HSPC129)是一个假设RNA-polymerase II carboxy-terminal domain (CTD)磷酸酶(1),这属于CTD磷酸酶的一个小亚家族(2)。RNA polymerase II的CTD包含多重的Y-S-P-T-S-P-S重复序列,该序列是在转录循环期间被磷酸化(3,4)。一般而言,在RNA合成的数个步骤和在转录后修饰期间,CTD磷酸酶调节RNA-polymerase II的可逆CTD磷酸化作用(4-6)。CTDSPL2蛋白在数个结构性和功能性类似与其它CTD磷酸酶,包括FCP1、SCP1、DULLARD和UBLCP1 (1,2)。
