Patent ID: 7183380

Claim:
An isolated polypeptide comprising an amino acid sequence selected from the group consisting of: (a) the amino acid sequence of SEQ ID NO:2; (b) an amino acid sequence selected from the group consisting of: amino acids 542 through 579 of SEQ ID NO:2, and amino acids 464 though 583 of SEQ ID NO:2; (c) an amino acid sequence selected from the group consisting of: amino acids 465 through 499 of SEQ ID NO:2, and amino acids 431 through 499 of SEQ ID NO:2; (d) an amino acid sequence selected from the group consisting of: amino acids 465 through 590 of SEQ ID NO:2, and amino acids 444 through 640 of SEQ ID NO:2; (e) a fragment of the amino acid sequences of any of (a)–(d) having IMX97018 polypeptide self-association or RNA-binding activity; (f) a fragment of the amino acid sequences of any of (a)–(d) comprising an AXH domain; and (g) an amino acid sequence having IMX97018 polypeptide self-association or RNA-binding activity, and sharing amino acid identity with the amino acid sequences of any of (b)–(f), wherein the percent amino acid identity is selected from the group consisting of: at least 80%, at least 85%, at least 90%, at least 95%, at least 97.5%, at least 99%, and at least 99.5%.
