Menin interacts with ARS2. A, silver staining of menin-containing fractions after affinity purification using anti-FLAG M2 beads in HEK293 cells ectopically expressing menin. Visible bands were excised for identification by mass spectroscopy. Asterisk indicates ARS2 peptide fragments identified by mass spectroscopy; MLDAAVIK, LTPLLSVR, NINGITQHK, RGWVTFDR, VALSEPQPER, SKYHPDEVGK, FVTSNTQELGK, VLDKLLLYLR, DLDAPDDVDFF, VRNINGITQHK, VALSEPQPERR, ISHGEVLEWQK, ESLSEEEAQKMGR, EVAFFNNFLTDAK, TFEEKLTPLLSVR, LGSIAEIDLGVPPPVMK, MLDAAVIKMEGGTENDLR, AIVEYRDLDAPDDVDFF, ILEQEEEEEQAGKPGEPSK, and ILEQEEEEEQAGKPGEPSKK. B, nuclear extract from HEK293 cells ectopically expressing menin were immunoprecipitated (IP) with anti-menin antibody, and immunoblotted for ARS2. Asterisk indicates a nonspecific band.
