Summary: Predicted to enable extracellular matrix protein binding activity and integrin binding activity. Involved in regulation of transforming growth factor beta activation. Acts upstream of or within several processes, including Langerhans cell differentiation; ganglioside metabolic process; and hard palate development. Part of integrin alphav-beta8 complex. Is expressed in several structures, including axial skeleton; hindlimb phalanx; nervous system; reproductive system; and sensory organ. Orthologous to human ITGB8 (integrin subunit beta 8).

RefSeqs maintained independently of Annotated Genomes

These reference sequences exist independently of genome builds. Explain

These reference sequences are curated independently of the genome annotation cycle, so their versions may not match the RefSeq versions in the current genome build. Identify version mismatches by comparing the version of the RefSeq in this section to the one reported in Genomic regions, transcripts, and products above.
