title: Cloning of a full-length complementary DNA for an Artemia salina glycine-rich protein. Structural relationship with RNA binding proteins.
abstract: Overlapping cDNAs have been isolated containing all the coding sequences for Artemia salina protein GRP33, a glycine-rich protein (16.6 mol % glycine), with a molecular weight of 32,992. GRP33 is closely related to HD40, the major protein component of Artemia heterogeneous nuclear ribonucleoprotein particles, and shares certain characteristics with other RNA binding proteins. The C-terminal region (123 amino acids) contains 39 glycine residues. This region has multiple arginine residues flanked by glycines, resembling the glycine-dimethylarginine clusters present in other RNA binding proteins. Secondary structure predictions for the protein reveal two distinct domains: a hydrophilic C-terminal domain with an extended conformation and a larger N-terminal domain with a number of alpha-helices and beta-sheets.
