PHYSICAL PROPERTIES

STRUCTURE

motifs/domains	NLI-interacting factor motif
	small C-terminal domain phosphatases that may control the RNA polymerase II transcription machinery (Kashuba 2004)

HOMOLOGY

interspecies	homolog to yeast hypothetical protein YA22
	ortholog to murine Ctdspl

Homologene

FAMILY	small C-terminal domain (CTD) phosphatase, SCP family
	NLIIF family

CATEGORY

chaperone/stress , enzyme

SUBCELLULAR LOCALIZATION	plasma membrane
	intracellular
	intracellular,nucleus

basic FUNCTION	catalyzing the dephosphorylation of Ser5 within the consensus repeat of RNA polymerase II
	may be functioning as coordinator of transcriptional activity
	is shown to involve in regulation of cell growth and differentiation and exhibits tumor suppressor activity
	CTDSPL and CTDSPL2 have oncogenic properties, including promoting cell migration

CELLULAR PROCESS

nucleotide, transcription, regulation
