Summary: Integrins are heterodimeric proteins made up of alpha and beta subunits. At least 18 alpha and 8 beta subunits have been described in mammals. Integrin family members are membrane receptors involved in cell adhesion and recognition in a variety of processes including embryogenesis, hemostasis, tissue repair, immune response and metastatic diffusion of tumor cells. This gene encodes a beta subunit. Multiple alternatively spliced transcript variants which encode different protein isoforms have been found for this gene. [provided by RefSeq, Jul 2008]

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.

Status: REVIEWED

Description

Transcript Variant: This variant (1D) includes an alternate exon, known as exon D, which results in a frameshift in the 3' coding region, compared to variant 1A. The resulting isoform (1D) has a distinct and longer C-terminus, compared to isoform 1A. This variant lacks full-length transcript support; its exon combination is predicted based on partial human transcript alignments, homologous transcript alignments including full-length cow mRNA BC114107.1, and data in the literature, including PMIDs 7544298, 7545396, 8567725 and 11779688, which consider this to be a functionally significant variant. This variant lacks a 5' UTR due to alternative splicing choices upstream of the CDS, and uncertainty about which alternative promoter is used.

Description

Transcript Variant: This variant (1E) differs in the 5' UTR compared to variant 1A. Both variants 1A and 1E encode the same isoform (1A). There are no publicly available full-length transcripts representing this variant; it is supported by partial transcript alignments and by full-length cloning and sequencing in PMID:8444890.
