|Other Names||Barrier-to-autointegration factor, Breakpoint cluster region protein 1, Barrier-to-autointegration factor, N-terminally processed, BANF1, BAF, BCRG1|
|Target/Specificity||The synthetic peptide sequence used to generate the antibody AP14071c was selected from the Center region of BANF1. A 10 to 100 fold molar excess to antibody is recommended. Precise conditions should be optimized for a particular assay.|
|Format||Synthetic peptide was lyophilized with 100% acetonitrile and is supplied as a powder. Reconstitute with 0.1 ml DI water for a final concentration of 1 mg/ml.|
|Storage||Maintain refrigerated at 2-8°C for up to 6 months. For long term storage store at -20°C.|
|Precautions||This product is for research use only. Not for use in diagnostic or therapeutic procedures.|
|Function||Plays fundamental roles in nuclear assembly, chromatin organization, gene expression and gonad development. May potently compress chromatin structure and be involved in membrane recruitment and chromatin decondensation during nuclear assembly. Contains 2 non-specific dsDNA-binding sites which may promote DNA cross-bridging.|
|Cellular Location||Barrier-to-autointegration factor: Nucleus Cytoplasm. Chromosome. Nucleus envelope. Note=Significantly enriched at the nuclear inner membrane, diffusely throughout the nucleus during interphase and concentrated at the chromosomes during the M-phase The phosphorylated form (by VRK1 or vaccinia virus B1 kinase) shows a cytoplasmic localization whereas the unphosphorylated form locates almost exclusively in the nucleus (PubMed:24600006, PubMed:16495336). May be included in HIV-1 virions via its interaction with viral GAG polyprotein|
|Tissue Location||Widely expressed. Expressed in colon, brain, heart, kidney, liver, lung, ovary, pancreas, placenta, prostate, skeletal muscle, small intestine, spleen and testis. Not detected in thymus and peripheral blood leukocytes|

The protein encoded by this gene was first identified byits ability to protect retroviruses from intramolecular integrationand therefore promote intermolecular integration into the host cellgenome. The protein forms a homodimer which localizes to both thenucleus and cytoplasm and is specifically associated withchromosomes during mitosis. This protein binds to double strandedDNA in a non-specific manner and also binds to LEM-domaincontaining proteins of the nuclear envelope. This protein isthought to facilitate nuclear reassembly by binding with both DNAand inner nuclear membrane proteins and thereby recruit chromatinto the nuclear periphery. Alternative splicing results in multipletranscript variants encoding the same protein.
