scpl-1 encodes, by alternative splicing, two protein isoforms of a putative class-C RNA polymerase II (RNAPII) carboxyl-terminal domain (CTD) phosphatase, orthologous to budding yeast PSR1 and PSR2 and human CTDSP1 (OMIM:605323), CTDSP2 (OMIM:608711, amplified in sarcoma), and CTDSPL (OMIM:608592, deleted in epithelial cancer), and paralogous to C. elegans SCPL-3 and human CTDSPL2; more distantly, SCPL-1 (and its paralog SCPL-3) are similar to SCPL-2, SCPL-4, and FCP-1; loss of scpl-1 activity via RNAi results in a slightly abnormal egg-laying response in the presence of serotonin; an scpl-1::gfp promoter fusion is expressed in pharyngeal, vulval, and body wall muscle; within body wall muscle, SCPL-1 localize to the M line and I band; SCPL-1 physically interacts with UNC-89 both in vitro and in vivo.
Enables several functions, including LIM domain binding activity; kinase binding activity; and protein-macromolecule adaptor activity. Involved in dephosphorylation and regulation of egg-laying behavior. Located in I band and M band. Expressed in body wall musculature; pharyngeal muscle cell; and vulval muscle. Human ortholog(s) of this gene implicated in lung non-small cell carcinoma. Is an ortholog of human CTDSP1 (CTD small phosphatase 1) and CTDSPL (CTD small phosphatase like).
Map position created from combination of previous interpolated map position (based on known location of sequence) and allele information. Therefore this is not a genetic map position based on recombination frequencies or genetic experiments. This was done on advice of the CGC.
