This entry represents the first type I KH RNA-binding domain of BICC/BICC1. Bicaudal-C from Drosophila melanogaster (BICC) and its homologues from vertebrates BICC1 are RNA-binding proteins with translational repression function; they regulate gene expression and modulate cell proliferation and apoptosis [1]. BICC1 is a negative regulator of Wnt signalling [2]. These proteins are involved in the regulation of embryonic differentiation and play a role in the regulation of Dvl (Dishevelled) signalling, particularly in the correct cilia orientation and nodal flow generation [3].
