Protein kinase C (PRKCA and PRKCB), activated by lipin-generated diacylglycerol (DAG), phosphorylates C-terminal tails of lamins (serine S395 in lamins A, B and C, and also serine S405 of lamin B), leading to depolymerization of lamin filaments (Hocevar et al. 1993, Goss et al. 1994, Mall et al. 2012).
