Bbs2 Gene Summary [Rat]
Predicted to enable RNA polymerase II-specific DNA-binding transcription factor binding activity. Predicted to be involved in several processes, including negative regulation of appetite by leptin-mediated signaling pathway; regulation of cilium beat frequency involved in ciliary motility; and visual perception. Predicted to act upstream of or within several processes, including blood vessel diameter maintenance; brain development; and cilium assembly. Predicted to be located in ciliary membrane; microvillus; and stereocilium. Predicted to be part of BBSome. Predicted to be active in several cellular components, including ciliary basal body; motile cilium; and neuron projection. Human ortholog(s) of this gene implicated in Bardet-Biedl syndrome; Bardet-Biedl syndrome 2; obesity; and retinitis pigmentosa 74. Orthologous to human BBS2 (Bardet-Biedl syndrome 2).

Protein Domains
A protein domain is a distinct structural or functional region within a protein that can evolve, function, and exist independently of the rest of the protein chain. These domains in rat Bbs2 often fold into stable, three-dimensional structures and are associated with specific biological functions, such as binding to DNA, other proteins, or small molecules.
