The flowering time control protein FCA is a RNA-binding protein and a critical component of the autonomous flowering pathway, which induces flowering by suppressing the floral repressor FLOWERING LOCUS C (FLC) [ 1 , 2 ]. It plays a role in alternative polyadenylation of its own pre-mRNA and antisense FLC RNA. It can also serve as a chromatin remodelling factor that mediates histone demethylation of FLC chromatin, causing suppression of FLC expression [ 3 ]. FCA contains two RNA recognition motifs (RRMs).

This entry represents the RNA recognition motif 2 (RRM2) of FCA.
