Oncogenic Ki-ras but not oncogenic Ha-ras blocks integrin beta1-chain maturation in colon epithelial cells.
Yan Z, Chen M, Perucho M, Friedman E. Yan Z, et al. J Biol Chem. 1997 Dec 5;272(49):30928-36. doi: 10.1074/jbc.272.49.30928. J Biol Chem. 1997. PMID: 9388239 Free article.
Human colorectal tumors commonly contain mutations in Ki-ras but rarely, if ever, in Ha-ras. The selectivity for Ki-ras mutations in this tumor was explored using the HD6-4 colon epithelial cell line which contains no ras mutations …

Lee YM, Jung SO, Seo JS, Yoon YD, Lee JS. Lee YM, et al. Mar Environ Res. 2006 Jul;62 Suppl:S136-40. doi: 10.1016/j.marenvres.2006.04.052. Epub 2006 Apr 18. Mar Environ Res. 2006. PMID: 16716392
By investigating expression patterns, we found that the R. marmoratus Ki-ras (Rm Ki-ras) gene showed an alternative splicing event between exons 4A and 4B according to tissue types, which is different from the expression pattern of mammalian Ki- …
