To read the full abstract: Science 2019;365:eaat7693.These authors performed a genome-wide association study on 493 001 participants of European-ancestry from the USA, UK, and Sweden to identify genes associated with sexual orientation. They found multiple loci implicated in same-sex sexual behavior indicating that, like other behavioral traits, non-heterosexual behavior is polygenic.As many as 4% to 10% of US individuals ...

It is involved in the formation of myosin phosphatase and is regulated by phosphorylation.<p cla...
