For example, in the case of the protein SIN3A, a
regulator of
gene transcription, the small molecule that covalently binds to its reactive lysine blocks the protein's function by disrupting SIN3A's interaction with another protein, TGIF1 — an interaction
implicated in some invasive breast cancers.
In addition, a number of key developmental
regulators were expressed at higher levels in bsl1 - 1 mutants, including orthologs of classical
genes from maize that specify AM identity and determinacy (e.g., bd1 [Chuck et al., 2002] and ramosa1 [Vollbrecht et al., 2005]-RRB-, that pattern lateral organ development (e.g., narrow sheath1 [Scanlon et al., 1996] and yabby10 [Juarez et al., 2004]-RRB-, and those
implicated in carpel repression in maize tassels (e.g., grassy tillers1 [Whipple et al., 2011], tasselseed 1 [Acosta et al., 2009], and tasselseed 2 [Irish and Nelson, 1993]-RRB-(Table 2).
