Promotes megakaryocyte differentiation by enhancing ERK and JNK signaling as well as up-regulating RUNX1 and FLI1 expression (PubMed:24681962). Represses NF-kappa-B transcriptional activity by inhibiting phosphorylation of RELA at ‘Ser-536’ (PubMed:24681962). May be involved in early neuronal development (By similarity).
