Homeobox protein cut-like 1 (CUX1) is also known as CCAAT displacement protein (CDP) and Homeobox protein cux-1. CUX1 is thought to repress expression of developmentally regulated genes involved in mammalian development, likely through the prevention of CCAAT factor binding at promoters. CUX1 also represses T-cell receptor (TCR) beta enhancer function by binding to matrix attachment region beta (MARbeta), and is a component of the nf-munr repressor, which binds to matrix attachment regions (MARs) of the immunoglobulin heavy chain enhancer.

Other homologies: Mouse (95% sequence homology).

This antibody recognizes the region of amino acids beginning at 861 of CUX1. This antibody is expected to cross react with all known isoforms of CUX1.

Evaluated by Western Blotting in HeLa nuclear extract.

Western Blotting Analysis: 0.25 µg/mL from a representative lot detected CUX1 in 10 µg of HeLa nuclear extract.

~200 kDa and ~110 kDa observed. Uniprot describes 11 different isoforms. A full length protein has been described at 200 kDa and is proteolytically cleaved into the p150, p110, p90, and p80 isoforms. Additionally, the p75 isoform is the result of alternative splicing (Sansregret, L, et al. (2008). Gene. 412(1-2):84-94.). Uncharacterized band(s) may be observed in some cell lysates.
