Protein function

Encodes a protein involved in RNA-mediated chromatin silencing.

Phenotype

Single mutant:
fca single mutant is late flowering under both SD and LD conditions. [Reeves et al., 2002][Martü¾™†”¼nez-Zapater et al., 1990][Sheldon et al., 2000][Macknight et al., 1997]

Remarks:
FCA acts together with FPA to prevent the expression of distally polyadenylated antisense RNAs from the FLC locus. [Michaels et al., 2001][Duc et al., 2013]

Remarks:
FCA requires FY and FLD to repress the expression of FLC through H3K4 demethylation. Its function also relies partially on DCL3. [Liu et al., 2007]

Overexpressor:
The overexpression of FCA leads to a slight but reproducible early-flowering phenotype under both SD and LD conditions. [Macknight et al., 2002][Macknight et al., 1997]

Function:
Plays a major role in the promotion of the transition of the vegetative meristem to reproductive development. Plays a role in the regulation of flowering time in the autonomous flowering pathway by decreasing FLOWERING LOCUS C mRNA levels. Required for RNA-mediated chromatin silencing of a range of loci in the genome. Cotranscriptionally recognizes aberrant RNA and marks it for silencing. Controls alternative cleavage and polyadenylation on pre-mRNAs and antisense RNAs. Acts redundantly with FPA to prevent the expression of distally polyadenylated antisense RNAs at the FLC locus.
