Summaries for LDB1 Gene

GeneCards Summary for LDB1 Gene

LDB1 (LIM Domain Binding 1) is a Protein Coding gene. Among its related pathways are Transcriptional misregulation in cancer. GO annotations related to this gene include protein homodimerization activity and enzyme binding. An important paralog of this gene is LDB2.

UniProtKB/Swiss-Prot for LDB1 Gene

  • Binds to the LIM domain of a wide variety of LIM domain-containing transcription factors. May regulate the transcriptional activity of LIM-containing proteins by determining specific partner interactions. Plays a role in the development of interneurons and motor neurons in cooperation with LHX3 and ISL1. Acts synergistically with LHX1/LIM1 in axis formation and activation of gene expression. Acts with LMO2 in the regulation of red blood cell development, maintaining erythroid precursors in an immature state (By similarity).

    Protein attributes for LDB1 Gene

    Size:
    411 amino acids
    Molecular mass:
    46533 Da
    Quaternary structure:
    • Forms homodimers and heterodimers. Interacts with and activates LHX1/LIM1. Interacts with the LIM domains of ISL1 and LMO2. Can assemble in a complex with LMO2 and TAL1/SCL but does not interact with TAL1/SCL directly. Strongly interacts with the LIM2 domain of LMX1A and more weakly with the LIM1 domain. Homodimerization is not required for, and does not effect, LMX1A-binding. Component of a nuclear TAL-1 complex composed at least of CBFA2T3, LDB1, TAL1 and TCF3. Interacts with LHX6 and LHX9. At neuronal promoters, forms a complex with LHX3 involved in the specification of interneurons, in motor neurons, it is displaced by ISL1 to form a ternary complex in which ISL1 contacts both LHX3 and LDB1 (By similarity). Interacts with ESR1. Interacts with SLK; leading to negatively regulate SLK kinase activity (By similarity).
    Miscellaneous:
    • Acts as a negative coregulator of ESR1-mediated transcription in breast cancer cells.
