Summary
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. Most isoforms share a common C-terminal domain, which contains two zinc finger motifs that are required for hetero- or homo-dimerization, and for interactions with other proteins. The isoforms, however, differ in the number of N-terminal zinc finger motifs that bind DNA and in nuclear localization signal presence, resulting in members with and without DNA-binding properties. Only a 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 are 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 2014]

    Description
    Transcript Variant: This variant (15) lacks five 3' exons but contains an alternate 3' terminal exon, and it thus differs in its 3' coding region and 3' UTR, compared to variant 1. The encoded isoform (15) has a distinct C-terminus and is significantly shorter than isoform 1. This isoform contains no N-terminal zinc finger motifs and is likely non-DNA-binding.

    See identical proteins and their annotated locations for NP_001278775.1

    Status: REVIEWED

    Description
    Transcript Variant: This variant (16) lacks five 3' exons but contains two alternate 3' exons, and it thus differs in its 3' coding region and 3' UTR, compared to variant 1. The encoded isoform (16) has a distinct C-terminus and is significantly shorter than isoform 1. This isoform contains no N-terminal zinc finger motifs and is likely non-DNA-binding. Both variants 16 and 17 encode isoform 16.

Suppressed Reference Sequence(s)

The following Reference Sequences have been suppressed. Explain

  1. NM_001220766.1: Suppressed sequence

    Description
    NM_001220766.1: This RefSeq was permanently suppressed because currently there is insufficient support for the transcript.
  2. NM_001220769.1: Suppressed sequence

    Description
    NM_001220769.1: This RefSeq was permanently suppressed because currently there is insufficient support for the transcript.
  3. NM_001220772.1: Suppressed sequence

    Description
    NM_001220772.1: This RefSeq was permanently suppressed because currently there is insufficient support for the transcript and the protein.
  4. NM_001220773.1: Suppressed sequence

    Description
    NM_001220773.1: This RefSeq was permanently suppressed because currently there is insufficient support for the transcript and the protein.
  5. NM_001220774.1: Suppressed sequence

    Description
    NM_001220774.1: This RefSeq was permanently suppressed because currently there is insufficient support for the transcript and the protein.
  6. NM_001220775.1: Suppressed sequence

    Description
    NM_001220775.1: This RefSeq was permanently suppressed because currently there is insufficient support for the transcript and the protein.
  7. NM_001220776.1: Suppressed sequence
