SNRNP200 encodes the human gene, Small nuclear ribonucleoprotein, U5 200kDa subunit. It may also be known as: U5 small nuclear ribonucleoprotein 200 kDa helicase; BRR2 homolog; U5 snRNP-specific 200 kDa protein; U5-200KD; Activating signal cointegrator 1 complex subunit 3-like 1; U5 small nuclear ribonucleoprotein 200 kDa helicase ; U5 snRNP specific protein, 200 KD; ASCC3L1; BRR2; HELIC2; RP33; small nuclear ribonucleoprotein 200kDa (U5). The encoded protein is an enzyme with an amino acid length of 2136 and a mass of 244.5 kDa. Other isoforms may exist. SNRNP200 is a member of the Helicase family, SKI2 subfamily. Homologs of this gene exist in other organisms, including: Mouse, Rat, Zebrafish, Frog, Chicken.
