label: RNA Recognition Motif
label_lc: rna recognition motif
description: "RNA Binding Domains (RBD) mediate the interaction of RNAs with RNA-binding proteins. RBDs of about 90 amino acids consist of a four-stranded beta sheet adjacent to two alpha helixes. Within RBDs, conserved RNP-1 and RNP-2 motifs on the central beta sheets lie side by side; their side chains contact RNA."
