Study tracked the post-weaning development of a motor phenotype that arose in mice after random insertion of a transgene into the genome. The transgene was later found to have disrupted the beta-IV spectrin gene, which was confirmed by reduced expression of betaIV spectrin protein in brain homogenates. The motor phenotype was recessive, occurring in 20% of L25+/-xL25+/- progeny.

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.

NM_001199234.1 → NP_001186163.1 spectrin beta chain, non-erythrocytic 4 isoform sigma6

See identical proteins and their annotated locations for NP_001186163.1

Status: VALIDATED

Description

Transcript Variant: This variant (sigma6a) has a shorter and distinct 5' terminus which results in the use of an in-frame downstream translation initiation signal, compared to sigma1. Compared to isoform sigma1, it encodes an isoform (sigma6) that lacks multiple calponin-homology domains and spectrin repeats at the N-terminus. Variants sigma6a-c encode the same protein.
