DiseaseSchizophrenia 9 (SCZD9) [MIM:604906]: A complex, multifactorial psychotic disorder or group of disorders characterized by disturbances in the form and content of thought (e.g. delusions, hallucinations), in mood (e.g. inappropriate affect), in sense of self and relationship to the external world (e.g. loss of ego boundaries, withdrawal), and in behavior (e.g bizarre or apparently purposeless behavior). 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. Some patients manifest schizophrenic as well as bipolar disorder symptoms and are often given the diagnosis of schizoaffective disorder. {ECO:0000269|PubMed:12023979, ECO:0000269|PubMed:14755443}. Note=Disease susceptibility is associated with variations affecting the gene represented in this entry.
FunctionInhibits 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.
PtmPalmitoylated on Cys-2 and/or Cys-12. {ECO:0000269|PubMed:10608901}.
PtmPhosphorylated by cyclic GMP-dependent protein kinase. {ECO:0000250}.
SimilarityContains 1 RGS domain. {ECO:0000255|PROSITE- ProRule:PRU00171}.
Tissue SpecificityExpressed 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. {ECO:0000269|PubMed:17707117}.
