资源简介:
Phosphorylation of LBR (lamin B receptor) at serine residue S71 drives binding of LBR to KPNB1 (importin beta) (Lu et al. 2010). This prevents premature association of nascent nuclear membranes with chromatin in anaphase (Tseng and Chen 2011). Dephosphorylation of this site is suggested to promote NE reassembly (Tseng and Chen 2011).
LBR(层B受体)的丝氨酸残基S71的磷酸化作用驱动LBR与KPNB1(输入蛋白β)的结合(Lu等,2010年)。此过程防止了新生核膜在后期与染色质的过早关联(Tseng和Chen,2011年)。该位点的去磷酸化被提议可促进细胞核的重组(Tseng和Chen,2011年)。
