disease:Genetic variation in RGS4 may be associated with susceptibility to schizophrenia 9 (SCZD9) [MIM:604906]. Schizophrenia [MIM:181500] is a psychosis, a disorder of thought and sense of self. Although it affects emotions, it is distinguished from mood disorders in which such disturbances are primary. Similarly, there may be mild impairment of cognitive function, and it is distinguished from the dementias in which disturbed cognitive function is considered primary. No objective biological test for schizophrenia exists. Schizophrenia is a common disorder with a lifetime prevalence of approximately 1%. It is highly heritable but the genetics are complex.,function:Inhibits signal transduction by increasing the GTPase activity of G protein alpha subunits thereby driving them into their inactive GDP-bound form. Activity on G(z)-alpha is inhibited by phosphorylation of the G-protein. Activity on G(z)-alpha and G(i)-alpha-1 is inhibited by palmitoylation of the G-protein.,PTM:Palmitoylated on Cys-2 and/or Cys-12.,PTM:Phosphorylated by cyclic GMP-dependent protein kinase.,similarity:Contains 1 RGS domain.,

Expressed in brain and heart. Expressed in brain at protein level. Expressed in prefontal and visual cortex. Isoform 4 and isoform 5 are expressed ubiquitously. Isoform 1, isoform 2 and isoform 3 are not expressed in the cerebellum.
