Summary: This gene encodes a beta polypeptide chain found in adult hemoglobin, which consists of a tetramer of two alpha chains and two beta chains, and which functions in the transport of oxygen to various peripheral tissues. This gene is one of a cluster of beta-hemoglobin genes that are distally regulated by a locus control region, and which are organized along the chromosome in the order of their developmental expression. In mouse, two major strain-specific haplotypes of the beta-globin gene cluster are found - a "single" haplotype found in C57BL/-type strains, which includes two highly similar adult beta-globin genes, beta s and beta t, and a "diffuse" haplotype found in strains such as BALB/c and 129Sv, which includes two somewhat diverse adult beta-globin genes, beta-major and beta-minor. This gene represents the beta-major adult gene found in the "diffuse" haplotype. Primary chromosome 7 of the mouse reference genome assembly, which is derived from C57BL/6 strain mice, represents the "single" haplotype, while the "diffuse" haplotype is represented in the reference genome collection by the BALB/c strain alternate contig, NT_095534.1. [provided by RefSeq, May 2013]
Annotation information: Note: In NCBI's Mus musculus Annotation Release 103, this haplotype-specific gene was incorrectly annotated on the chromosome 7 (NC_000073.6) primary reference genome assembly. It has been determined that this Hbb-b1 gene represents an adult beta-globin gene of the "diffuse" haplotype, and therefore its annotation belongs on the alternate contig, NT_095534.1. The primary reference genome allele represents the "single" haplotype (PMID:7237554), and the Hbb-bt gene (GeneID:101488143) should instead be annotated at this NC_000073.6 location. Correct annotation of these haplotype-specific genes is expected following future annotation releases. [17 Jun 2014]; not in current annotation release

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.
