Abstract

A region-specific, trans-acting regulatory gene that alters in vivo protein levels of alpha-glycerophosphate dehydrogenase (alpha-GPDH) has been mapped to position 55.4 on the third chromosome of Drosophila melanogaster. The gene has been found to affect the in vivo stability of alpha-GPDH in adult thoracic tissue but has no effect on alpha-GPDH levels in the abdomen. Although no other thoracic proteins were found to be influenced by the locus, it appears to modify the level of one additional abdominal protein. The action of the gene over development and its possible mode of control are discussed.

摘要

一个位于果蝇第三号染色体 55.4 位置的、具有组织特异性和反式作用的调控基因,能够改变体内α-甘油磷酸脱氢酶(α-GPDH)的蛋白水平。该基因已被发现影响成年果蝇胸部组织中α-GPDH 的体内稳定性,但对腹部的α-GPDH 水平没有影响。虽然没有发现其他胸部蛋白受该基因座影响,但它似乎可以改变一种额外的腹部蛋白的水平。该基因在发育过程中的作用及其可能的控制模式正在讨论中。
