Disease

[ROA1_HUMAN] Amyotrophic lateral sclerosis;Inclusion body myopathy with Paget disease of bone and frontotemporal dementia. The disease is caused by mutations affecting the gene represented in this entry.^[1] The disease is caused by mutations affecting the gene represented in this entry.^[2]

Function

[ROA1_HUMAN] Involved in the packaging of pre-mRNA into hnRNP particles, transport of poly(A) mRNA from the nucleus to the cytoplasm and may modulate splice site selection. May play a role in HCV RNA replication.^[3]

Publication Abstract from PubMed

The RNA-recognition motif (RRM) is a common and evolutionarily conserved RNA-binding module. Crystallographic and solution structural studies have shown that RRMs adopt a compact alpha/beta structure, in which four antiparallel beta-strands form the major RNA-binding surface. Conserved aromatic residues in the RRM are located on the surface of the beta-sheet and are important for RNA binding. To further our understanding of the structural basis of RRM-nucleic acid interaction, we carried out a high resolution analysis of UP1, the N-terminal, two-RRM domain of heterogeneous nuclear ribonucleoprotein A1 (hnRNP A1), whose structure was previously solved at 1.75-1.9 A resolution. The two RRMs of hnRNP A1 are closely related but have distinct functions in regulating alternative pre-mRNA splice site selection. Our present 1.1 A resolution crystal structure reveals that two conserved solvent-exposed phenylalanines in the first RRM have alternative side chain conformations. These conformations are spatially correlated, as the individual amino acids cannot adopt each of the observed conformations independently. These phenylalanines are critical for nucleic acid binding and the observed alternative side chain conformations may serve as a mechanism for regulating nucleic acid binding by RRM-containing proteins.

Correlated alternative side chain conformations in the RNA-recognition motif of heterogeneous nuclear ribonucleoprotein A1.,Vitali J, Ding J, Jiang J, Zhang Y, Krainer AR, Xu RM Nucleic Acids Res. 2002 Apr 1;30(7):1531-8. PMID:11917013^[4]
