The Fanconi Anemia (FA) core complex provides the essential E3 ligase function for the FA pathway activation through the spatially defined FANCD2 ubiquitination. Of the seven FA gene products forming the core complex, FANCL possesses a RING domain with demonstrated E3 ligase activity. The other six components have no clearly defined roles. Through epistatic analyses, we identified three functional modules in the FA core complex: a catalytic module consisting of FANCL, FANCB, and FAAP100 is absolutely required for the E3 ligase function; the FANCA-FANCG-FAAP20 module and the FANCC-FANCE-FANCF module provide non-redundant and ancillary functions supporting the chromatin and DNA damage association of the catalytic module. Disruption of the catalytic module renders total loss of the core complex function whereas loss of any ancillary module component does not. Our work revealed the roles of several FA gene products with previously undefined functions and a modularized assembly of the FA core complex.
