Comments concerning this interaction

Source was S2R+ cell line; bait produced from tagged transgenic construct; prey produced from endogenous gene.

(Carnesecchi et al., 2022)

Expression of wildtype Ubx results in enrichment of constitutively expressed exon 2 and alternatively spliced exon 4 of His3.3B. The Ubx N51A mutation significantly decreases enrichment of exon 2 and 4 of His3.3B.
