General description

Ser-Arg-rich (SR) proteins make up a family of functionally and structurally conserved phosphoproteins, and are required components of alternative and constitutive pre-mRNA splicing. SR proteins are characterized by their modular composition consisting of two domains of interest: an N-terminal RNA recognition motif (RRM) which serves in the determination of DNA-binding specificity, and the RS domain, an arginine and serine rich, C-terminal domain that serves as a shuttling and localization director of SR proteins and as a splicing activation domain. They are involved in various aspects of pre-mRNA splicing and in spliceosome assembly including; the identification and appropriation of splice-sites, and the manipulation of alternative splicing regulation.

Immunogen

Purified oocyte nuclei containing xenopus SR proteins.
