Ribonuclease H2 subunit A (RNASEH2A) is a member of the RNase HII family and eukaryotic subfamily. RNASEH2A Plays a part in DNA replication, probably by mediating the removal of lagging-strand Okazaki fragment RNA primers throughout DNA replication. RNASEH2A catalyzes the endonucleolytic cleavage of RNA to a 5�-phosphomonoester and is capable to bind magnesium or manganese as cofactors. Aicardi-Goutieres syndrome type 4 (AGS4) caused by defects in RNASEH2A.

RNASEH2A�Recombinant produced in E.coli is a single, non-glycosylated polypeptide chain containing 322 amino acids (1-299) and having a molecular mass of 35.8kDa.RNASEH2A is fused to a 23 amino acid His-tag at N-terminus & purified by proprietary chromatographic techniques.

UniProt Protein Function:RNASEH2A: Catalytic subunit of RNase HII, an endonuclease that specifically degrades the RNA of RNA:DNA hybrids. Participates in DNA replication, possibly by mediating the removal of lagging- strand Okazaki fragment RNA primers during DNA replication. Mediates the excision of single ribonucleotides from DNA:RNA duplexes. Defects in RNASEH2A are the cause of Aicardi-Goutieres syndrome type 4 (AGS4). A form of Aicardi-Goutieres syndrome, a genetically heterogeneous disease characterized by cerebral atrophy, leukoencephalopathy, intracranial calcifications, chronic cerebrospinal fluid (CSF) lymphocytosis, increased CSF alpha-interferon, and negative serologic investigations for common prenatal infection. Clinical features as thrombocytopenia, hepatosplenomegaly and elevated hepatic transaminases along with intermittent fever may erroneously suggest an infective process. Severe neurological dysfunctions manifest in infancy as progressive microcephaly, spasticity, dystonic posturing and profound psychomotor retardation. Death often occurs in early childhood. Belongs to the RNase HII family. Eukaryotic subfamily.

NCBI Summary:The protein encoded by this gene is a component of the heterotrimeric type II ribonuclease H enzyme (RNAseH2). RNAseH2 is the major source of ribonuclease H activity in mammalian cells and endonucleolytically cleaves ribonucleotides. It is predicted to remove Okazaki fragment RNA primers during lagging strand DNA synthesis and to excise single ribonucleotides from DNA-DNA duplexes. Mutations in this gene cause Aicardi-Goutieres Syndrome (AGS), a an autosomal recessive neurological disorder characterized by progressive microcephaly and psychomotor retardation, intracranial calcifications, elevated levels of interferon-alpha and white blood cells in the cerebrospinal fluid.[provided by RefSeq, Aug 2009]
