General description
CEACAM1 (carcinoembryonic antigen-related cell adhesion molecule 1) is thought to be a member of the immunoglobulin superfamily and is known as an epithelial tumor suppressor and an angiogenic growth factor. It has also been linked to the actin-based cytoskeleton. CEACAM1 is also known as a cellular receptor for a number of human mucosa pathogenic bacteria. The loss of activity of CEACAM1 has been related to the development of colorectal cancer.
~160 kDa observed. Target band size appears larger than the calculated molecular weights of 57.56/53,80 kDa (pro-/mature isoform 1; BGPa, CEACAM1-4L, TM1-CEA), 45.95/42.19 kDa (pro-/mature isoform 2; BGPg, CEACAM1-4C1), 35.30/31.54 kDa (pro-/mature isoform 3; BGPh, CEACAM1-3), 38.58/34.81 kDa (pro-/mature isoform 4; BGPi, CEACAM1-3C2), 50.35/46.58 kDa (pro-/mature isoform 5; BGPy, CEACAM1-3AL), 46.91/43.15 kDa (pro-/mature isoform 6; BGPb, CEACAM1-3L, TM2-CEA), 27.43/23.67 kDa (pro-/mature isoform 7; BGPx, CEACAM1-1L), 50.52/46.76 kDa (pro-/mature isoform 8; BGPc, CEACAM1-4S, TM3-CEA), 43.06/39.30 kDa (pro-/mature isoform 9; BGPz, CEACAM1-3AS), 51.15/47.38 kDa (pro-/mature isoform 10), 39.87/36.11 kDa ((pro-/mature isoform 11; BGPd, CEACAM1-3S) due to glycosylation. Uncharacterized bands may be observed in some lysates.
