- TranscriptVariant：This variant (7) lacks two in-frame coding exons, and uses an alternate in-frame donor splice site at another coding exon compared to variant 1. This results in a shorter isoform (7, also known as Ik-4(del) as described by Ezzat et al. in PMID:12937159) missing three internal protein segments compared to isoform 1. This isoform contains only two N-terminal zinc finger motifs, and represents a non-DNA-binding, dominant negative isoform (PMID:9892693).
- 基因简介：This gene encodes a transcription factor that belongs to the family of zinc-finger DNA binding proteins associated with chromatin remodeling. The expression of this protein is restricted to the fetal and adult hemo-lymphopoietic system, and it functions as a regulator of lymphocyte differentiation. Several alternatively spliced transcript variants encoding different isoforms have been described for this gene. All isoforms share a common C-terminal domain, which contains two zinc finger motifs that are required for hetero- or homodimerization, and for interactions with other proteins. The isoforms, however, differ in the number of N-terminal zinc finger motifs that bind DNA and contain the nuclear localization signal, resulting in members with and without DNA-binding properties. Only few isoforms contain the requisite three or more N-terminal zinc motifs that confer high affinity binding to a specific core DNA sequence element in the promoters of target genes. The non-DNA-binding isoforms are largely found in the cytoplasm, and thought to function as dominant negative factors. Overexpression of some dominant-negative isoforms have been associated with B-cell malignancies, such as acute lymphoblastic leukemia (ALL). [provided by RefSeq, May 2011]
