Summary: Predicted to enable lamin binding activity and protein serine/threonine phosphatase activity. Predicted to be involved in double-strand break repair via homologous recombination; negative regulation of protein phosphorylation; and regulation of double-strand break repair via homologous recombination. Located in cytoplasm and nucleus. Part of protein phosphatase 4 complex. Is expressed in several structures, including brain; neural retina; olfactory epithelium; and thymus primordium. Used to study oligoasthenoteratozoospermia. Orthologous to human PPP4C (protein phosphatase 4 catalytic subunit). [provided by Alliance of Genome Resources, Nov 2024]

LCMT-1 homozygous knock-out MEFs exhibited hyperphosphorylation of HDAC3, a reported target of the methylation-dependent PP4R1-PP4c complex. Collectively, our data suggest that LCMT-1 coordinately regulates the carboxyl methylation of PP2A-related phosphatases and, consequently, their holoenzyme assembly and function.

RefSeqs maintained independently of Annotated Genomes

These reference sequences exist independently of genome builds. Explain

These reference sequences are curated independently of the genome annotation cycle, so their versions may not match the RefSeq versions in the current genome build. Identify version mismatches by comparing the version of the RefSeq in this section to the one reported in Genomic regions, transcripts, and products above.
