Phosphatase Family OCA

Phosphatase Classification: Superfamily CC1: OCA

The OCA family is named after the five member genes in yeast (OCA1-5 = Oxidant-induced Cell-cycle Arrest). Yeast OCA members are involved in cell cycle arrest in response to oxidative damage[1], in telomere capping [2], in actin organization [3]. OCA3 has been shown to control intracellular localization of Gln3 (a phosphorylated transcriptional activator), in cooperation with Npr1 kinase [4].

It is found in most eukaryotes other than eumetazoa. We have seen it in fungi, plants, protists, monosiga, and sponge.

The family is also called plant and fungi atypical (PFA)-DSPs [5, 6].
