Summary: Contributes to cell adhesion molecule binding activity. Involved in several processes, including leukocyte migration involved in inflammatory response; positive regulation of NF-kappaB transcription factor activity; and positive regulation of nitric oxide biosynthetic process. Located in cell surface. Used to study nephritis and pneumonia. Biomarker of allergic rhinitis. Human ortholog(s) of this gene implicated in coronary restenosis; leukocyte adhesion deficiency; and leukocyte adhesion deficiency 1. Orthologous to human ITGB2 (integrin subunit beta 2).

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.
