HMT1/YBR034C Summary Help

Standard Name HMT1 1
Systematic Name YBR034C
Alias HCP1 , ODP1 2 , RMT1 3
Feature Type ORF, Verified
Description Nuclear SAM-dependent mono- and asymmetric arginine dimethylating methyltransferase that modifies hnRNPs, including Npl3p and Hrp1p, affecting their activity and nuclear export; methylates U1 snRNP protein Snp1p and ribosomal protein Rps2p; interacts genetically with genes encoding components of Rpd3(L) and this interaction is important for Rpd3 recruitment to the subtelomeric region. (1, 3, 4, 5, 6, 7, 8)
