This entry contains proteins with a BING4-like, C-terminal domain. WD repeat-containing protein 46 (WDR46) is a component of the nuclear scaffold, which is an insoluble structure that contributes to the inner nuclear organization. WDR46 is a fundamental scaffold component of the nucleolar structure, binding nucleolin and DDX21 []. Also in this family is U3 small nucleolar RNA-associated protein 7 (UTP7) from baker's yeast, which is involved in nucleolar processing of pre-18S ribosomal RNA [].
