Anti-MCM2 (Minichromosome maintenance complex component 2, BM28, CCNL1, cdc19, CDCL1, D3S3194, DNA r

MCM2 (Minichromosome maintenance protein 2, also BM28) is a member of the MCM family of proteins. Although its predicted MW is 102kD, it runs anomalously at 125kD in SDS-PAGE. MCM2 forms a large, 450-600kD prereplication complex with MCM3 through 7 plus HBO1, and associates with the ORC to initiate DNA synthesis. Human MCM2 is 904 amino acids (aa) in length (Accession # P49736). It contains one C4-type zinc finger region (aa329-355) and a P-loop NTPase region (aa485-659) and at least 12 Ser/Thr phosphorylation sites in the N-terminal one-third of the molecule. MCM2 has several potential isoforms. There is an alternate start site at Met10 with or without a 47 aa substitution for aa 109-157, a deletion of aa 31-126, a Gly substitution for aa 113-132 coupled with a 69 aa insertion after Lys476, and a seven aa substitution for aa1-137. Over aa143-296, human MCM2 shares 99% aa identity with mouse MCM2. Applications: Suitable for use in Western Blot. Other applications not tested.
