Web16 okt. 2024 · Homeobox proteins are a large superfamily of transcription factors (TFs) found in invertebrates, vertebrates, fungi, and plants, which contain a highly conserved DNA-binding domain known as the homeodomain (HD) [ 2 ]. The HD is 60 amino acids in length and adopts a structure of three α-helices connected by a loop and a turn [ 2, 3, 4 ]. Webprotein LMO2 or LIM-HD protein Xlim-1 were shown to inhibit RLIM-mediated turnover of Ldb1, suggesting its LIM protein partners regulate Ldb1 levels in vivo (Osten-dorff et al. 2002; Hiratani et al. 2003).
