Enzyme Name (EC)
type II protein arginine methyltransferase (2.1.1.320)
Gene Summary
capsuleen (csul) encodes a protein arginine methyltransferase that carries out symmetric dimethylation of arginine residues. It forms a complex with the product of vls, which is the substrate recognition subunit. Primary substrates for this complex include the spliceosomal Sm proteins. The products of csull and vls function in germline specification and are required for proper localization of the product of tud to the posterior pole of the oocyte.

Gene Group (FlyBase)
PROTEIN ARGININE N-METHYLTRANSFERASES -
Protein arginine methyltransferases catalyze the addition of one or two methyl groups to arginine. (Adapted from FBrf0174380 and FBrf0193526).
Protein Function (UniProtKB)
Arginine methyltransferase that can both catalyze the formation of omega-N monomethylarginine (MMA) and symmetrical dimethylarginine (sDMA) (By similarity). Specifically mediates the symmetrical dimethylation of arginine residues in the small nuclear ribonucleoproteins SmD1 and SmD3. Required for arginine symmetrical dimethylation of piwi family proteins, piwi, aub and AGO3, during germline development. Required during oogenesis for pole cell formation in the pathway controlled by oskar (osk) and for abdominal segments during early embryogenesis. Involved in nanos (nos) and germ cell mRNAs localization.
(UniProt, Q9U6Y9)
Summary (Interactive Fly)

protein arginine methyltransferase - together with its partner Valois Capsuléen is involved in protein localization in germ cells - required for the localization of specific components of the nuage and pole plasm, and in particular of Tudor

Model Confidence:
  • Very high (pLDDT > 90)
  • Confident (90 > pLDDT > 70)
  • Low (70 > pLDDT > 50)
  • Very low (pLDDT < 50)

AlphaFold produces a per-residue confidence score (pLDDT) between 0 and 100. Some regions with low pLDDT may be unstructured in isolation.
