ras基因家族的三个特征明确的基因H-ras、K-ras和N-ras编码密切相关的21-kD蛋白,这些蛋白在生长信号的转导中起作用。当基因中的点突变导致关键位置12、13或61中的一个氨基酸被替换时,ras蛋白获得转化潜力。正常蛋白质的过度表达,通常与基因扩增有关,也有类似的作用。
The three well-characterized genes of the ras gene family H-ras, K-ras, and N-ras, code for closely related 21-kDproteins that have a role In the transduction of growth signals. The ras proteins acquire transforming potential when a point mutation In the gene leads to replacement of an amino acid In one of the critical positions 12, 13, or 61. Overexpresslon of the normal protein, usually associated with gane amplification, can havesimilar effeCt8.
