Summary: Enables myosin phosphatase activity. Involved in several processes, including oogenesis; regulation of actomyosin contractile ring contraction; and regulation of signal transduction. Part of protein phosphatase type 1 complex. Is expressed in several structures, including adult brain; adult brain cell body rind; adult head; embryonic/larval dorsal vessel; and germarium. Human ortholog(s) of this gene implicated in Noonan syndrome-like disorder with loose anagen hair 2. Orthologous to human PPP1CB (protein phosphatase 1 catalytic subunit beta).

What's a GeneRIF?

flw is a key regulator of basal myosin oscillations and cell contractions underlying egg chamber elongation.
Title: Myosin light-chain phosphatase regulates basal actomyosin oscillations during morphogenesis.
Flw functions together with myosin phosphatase 1beta to negatively regulate myosin activity during ring canal formation in oogenesis.
Title: Protein phosphatase 1ß limits ring canal constriction during Drosophila germline cyst formation.
Drosophila melanogaster protein phosphatase type 1 beta (flapwing) co-regulates dephosphorylation and altered activity of both Merlin and Moesin.
Title: The PP1 phosphatase flapwing regulates the activity of Merlin and Moesin in Drosophila.
identified a loss-of-function mutation of flapwing, which encodes the catalytic subunit of protein phosphatase 1beta (PP1beta) that disrupts oocyte polarization
Title: Regulation of somatic myosin activity by protein phosphatase 1β controls Drosophila oocyte polarization.
Overexpression of the PP1 alpha isozymes does not rescue semilethal PP1 beta 9C mutants, whereas overexpression of either PP1 alpha 96A or PP1 beta 9C does rescue a lethal PP1 alpha 87B mutant combination.
Title: Essential, overlapping and redundant roles of the Drosophila protein phosphatase 1 alpha and 1 beta genes.
a Jun N-terminal kinase (JNK) mutant suppresses the semilethality of a strong flw allele
Title: The nonmuscle myosin phosphatase PP1beta (flapwing) negatively regulates Jun N-terminal kinase in wing imaginal discs of Drosophila.
Data show that Drosophila PP1beta, a specific isoform of serine/threonine protein phosphatase 1 (PP1), regulates nonmuscle myosin and that this is the essential role of PP1beta.
Title: The essential role of PP1beta in Drosophila is to regulate nonmuscle myosin.
Results suggest that protein phosphatase 1beta9C and Trithorax cooperate in Drosophila wing development.
