Anti-Dis2 (S. pombe) Antibody (D2F), Rabbit Serum


SKU: 63-119 Research Area: Applications:


Schizosaccharomyces pombe Dis2 is a serine/threonine protein phosphatase which is highly similar to mammalian type 1 phosphatase (PP1). Protein phosphatases are known to play critical roles in cell cycle regulation in fission yeast. Fission yeast has two type 1 protein phosphatases, Dis 2 and Sds21. They are 37 kDa proteins and their amino acid sequences are 80% identical to each other and to mammalian PP1 homologs. Dis 2 and Sds21 are necessary for mitotic chromosome disjunction and have overlapping functions. Their disruptants are lethal only when both genes are disrupted. Dis2 is known to be enriched in nuclei.
