What's a GeneRIF?

Data show no autoantibody production was detectable in surrogate light chain (SLC) components VpreB/CD179a and lambda5/CD179b transgenic mice.
Title: Surrogate light chain expression beyond the pre-B cell stage promotes tolerance in a dose-dependent fashion.
VpreB probes the fitness of newly generated VH domains of IgH chains for later pairing with IgL chains, and its non-Ig part fixes the preBCRs on the surface.
Title: The non-Ig parts of the VpreB and λ5 proteins of the surrogate light chain play opposite roles in the surface representation of the precursor B cell receptor.
The epigenetic profile of immunoglobulin light chain (IgL) genes is strongly influenced by pre-B cell receptor signaling and by the differentiative stage of the progenitor lymphocytes.
Title: The epigenetic profile of Ig genes is dynamically regulated during B cell differentiation and is modulated by pre-B cell receptor signaling.
Multiple receptor-dependent mechanisms operating at all stages of B cell development limit the contribution of B cells with Dmu heavy chain alleles to the repertoire.
Title: Multiple levels of selection responsive to immunoglobulin light chain and heavy chain structures impede the development of Dmu-expressing B cells.
Mice triply deficient for VpreB1 show B cell developmental defects but functional allelic exclusion of the IgH locus.
Title: VpreB1/VpreB2/lambda 5 triple-deficient mice show impaired B cell development but functional allelic exclusion of the IgH locus.
To identify the sequences that regulate lambda5 and VpreB1 expression during B cell development, the DNaseI hypersensitive sites in the lambda5-VpreB1 functional domain were mapped.

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.
