Protein function

RNA-binding protein that plays a central role in myelinization . Binds to the 5′-NACUAAY-N(1,20)-UAAY-3′ RNA core sequence. Regulates target mRNA stability . In addition, acts by regulating pre-mRNA splicing, mRNA export and protein translation. Required to protect and promote stability of mRNAs such as MBP and CDKN1B. Regulator of oligodendrocyte differentiation and maturation in the brain that may play a role in myelin and oligodendrocyte dysfunction in schizophrenia . Participates in mRNA transport by regulating the nuclear export of MBP mRNA. Also involved in regulation of mRNA splicing of MAG pre-mRNA. Acts as a translational repressor (By similarity).

Protein tissue specificity

Expressed in the frontal cortex of brain. Down-regulated in the brain of schizophrenic patients.

Protein sequence and domain

The KH domain and the Qua2 region are involved in RNA binding.Contains 1 KH domain.

Protein post-translational modifications

Methylated by PRMT1.; Tyrosine phosphorylated at its C-terminus, probably by FYN. Phosphorylation leads to decreased mRNA-binding affinity, affecting transport and/or stabilization of MBP mRNA (By similarity).

Protein cellular localization

Nucleus . Cytoplasm .


The protein encoded by this gene is an RNA-binding protein that regulates pre-mRNA splicing, export of mRNAs from the nucleus, protein translation, and mRNA stability. The encoded protein is involved in myelinization and oligodendrocyte differentiation and may play a role in schizophrenia. Multiple transcript variants encoding different isoforms have been found for this gene.
