DescriptionAnti-FOXP1 Antibody
Alternate Names

  • forkhead box P1
  • glutamine-rich factor 1
Background InformationForkhead box protein 1 (FOXP1) is a member of the Forkhead family of transcription factors, which have been characterized as transcriptional repressors and activators, and as having a DNA-binding domain distinguished by its formation of a winged-helix motif. FOXP1 is known to be an important regulator of airway morphogenesis, lung epithelial development, and early cardiac development. It is also known to have an important role in conjunction with NFκβ in the development of B-cells and the differentiation of macrophages. Splice variants give rise to four isoforms of FOXP1. The protein is known to form homodimers and heterodimers with FOXP2 and FOXP4. Studies have indicated FOXP1 as a potential inducer of oncogenesis when over expressed. The depletion and mutation of FOXP1 expression may lead to defects in embryonic cardiac, lung and esophagus epithelial development.

Entrez Gene Number
Entrez Gene SummaryThis gene belongs to subfamily P of the forkhead box (FOX) transcription factor family. Forkhead box transcription factors play important roles in the regulation of tissue- and cell type-specific gene transcription during both development and adulthood. Forkhead box P1 protein contains both DNA-binding- and protein-protein binding-domains. This gene may act as a tumor suppressor as it is lost in several tumor types and maps to a chromosomal region (3p14.1) reported to contain a tumor suppressor gene(s). Alternative splicing results in multiple transcript variants encoding different isoforms. [provided by RefSeq].

UniProt Number
UniProt SummaryFUNCTION: Transcriptional repressor that plays an important role in the specification and differentiation of lung epithelium. Can act with CTBP1 to synergistically repress transcription but CTPBP1 is not essential. Essential transcriptional regulator of B cell development (By similarity).

SUBUNIT STRUCTURE: Forms homodimers and heterodimers with FOXP2 and FOXP4. Dimerization is required for DNA-binding. Interacts with CTBP1 (By similarity).

SUBCELLULAR LOCATION: Nucleus Probable.

DOMAIN: The leucine-zipper is required for dimerization and transcriptional repression By similarity.

INVOLVEMENT IN DISEASE: A chromosomal aberration involving FOXP1 is found in acute lymphoblastic leukemia. Translocation t(9;3)(p13;p14.1) with PAX5.

SEQUENCE SIMILARITIES: Contains 1 C2H2-type zinc finger.

Contains 1 fork-head DNA-binding domain.

SEQUENCE CAUTION: The sequence AAF36135.1 differs from that shown. Reason: Frameshift at positions 531 and 545.
Molecular WeightFOXP1 has 4 isoforms observed at 75/73, 64 and 54 kDa.
