Ldb1 | LIM domain-binding protein 1; 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. (411 aa) | ||||
Prdm8 | PR domain zinc finger protein 8; Probable histone methyltransferase, preferentially acting on 'Lys-9' of histone H3. Histone methyltransferase activity has not been confirmed in other species. Involved in the control of steroidogenesis through transcriptional repression of steroidogenesis marker genes such as CYP17A1 and LHCGR. Forms with BHLHE22 a transcriptional repressor complex controlling genes involved in neural development and neuronal differentiation. In the retina, it is required for rod bipolar and type 2 OFF-cone bipolar cell survival. (688 aa) |
