Summary: Enables IgA binding activity and protein-macromolecule adaptor activity. Contributes to immunoglobulin receptor binding activity. Predicted to be involved in several processes, including defense response to symbiont; glomerular filtration; and positive regulation of respiratory burst. Part of dimeric IgA immunoglobulin complex. Is expressed in intestine; serum; and spleen. Orthologous to human JCHAIN (joining chain of multimeric IgA and IgM). [provided by Alliance of Genome Resources, Dec 2024]
Expression: Biased expression in large intestine adult (RPKM 384.0), small intestine adult (RPKM 358.4) and 3 other tissues See more

What's a GeneRIF?

Data show that Crlz1 increased the IgJ enhancer activity due to its CBF sites, as verified by both the absence of Crlz1 effect on the CBF-site mutated IgJ enhancer and the presence of transcriptional synergy between Crlz1 and CBFbeta.
Title: Crlz1 activates transcription by mobilizing cytoplasmic CBFbeta into the nucleus.
identifies the HSS3/4 enhancer of Crlz1-IgJ locus as another target of EBG in early developmental stage of B cells
Title: The HSS3/4 enhancer of Crlz1-IgJ locus is another target of EBF in the pre-B cell stage of B cell development.
H3 and H4 histones toward the chromatin of the Crlz1 gene are found to be hyperacetylated, especially on H3, in the pre-B cells, whereas those toward the chromatin of the IgJ gene are found to be hyperacetylated in the plasma cells
Title: Stage-specific expression of two neighboring Crlz1 and IgJ genes during B cell development is regulated by their chromatin accessibility and histone acetylation.

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.
