== Publication Abstract from PubMed == | |||
CTNNBL1 is a spliceosome-associated protein that binds nuclear localization signals (NLSs) in splice factors CDC5L and Prp31 as well as the antibody diversifying enzyme AID. Here, crystal structures of human CTNNBL1 reveal a distinct structure from its closest homologue karyopherin-alphas. CTNNBL1 comprises a HEAT-like domain (including a nuclear export signal), a central armadillo domain, and a coiled-coil C-terminal domain. Structure-guided mutations of the region homologous to the karyopherin-alpha NLS-binding site fail to disrupt CTNNBL1-NLS interactions. Our results identify CTNNBL1 as a unique selective NLS-binding protein with striking differences from karyopherin-alphas. | |||
Structural and mutational analysis reveals that CTNNBL1 binds NLSs in a manner distinct from that of its closest armadillo-relative, karyopherin alpha,Ganesh K, van Maldegem F, Telerman SB, Simpson P, Johnson CM, Williams RL, Neuberger MS, Rada C FEBS Lett. 2013 Nov 20. pii: S0014-5793(13)00847-8. doi:, 10.1016/j.febslet.2013.11.013.
