AMP脱氨酶是真核生物中普遍存在的一种酶,在能量代谢中起着重要作用。在本研究中,RNase保护分析和免疫沉淀与组织特异性抗血清被用来检查的成绩单和AMP脱氨酶在体内肌细胞分化过程中产生的肽在体外。在胚胎肌肉和未分化的成肌细胞中,3.4-腺苷酸酶(kb)转录物编码78千道尔顿(kDa)AMP脱氨酶肽,其与从成年动物的肾脏纯化的AMP脱氨酶同种型产生的抗血清交叉反应。在围产期的肌肉和肌细胞在体外分化的中间阶段,产生一个2.5 kb的成绩单,它编码一个77.5 kDa的AMP脱氨酶肽,与抗血清的异构体从成人心肌纯化的交叉反应。大约在出生时,另一个2.5 kb的AMP脱氨酶转录,编码80 kDa的肽成为可检测的。该肽与从成人骨骼肌中纯化的主要同种型的抗血清发生交叉反应。
AMP deaminase, a ubiquitous enzyme in eucaryotes, plays a central role in energy metabolism. In the present study, RNase protection analyses and immunoprecipitation with tissue-specific antisera were used to examine the transcripts and peptides of AMP deaminase produced during myogenesis in vivo and during myocyte differentiation in vitro. In embryonic muscle and undifferentiated myoblasts, a 3.4-kilobase (kb) transcript encoded a 78-kilodalton (kDa) AMP deaminase peptide that cross-reacted with antisera raised to the AMP deaminase isoform purified from kidney of the adult animal. In perinatal muscle and myocytes at an intermediate stage of differentiation in vitro, a 2.5-kb transcript was produced, and it encoded a 77.5-kDa AMP deaminase peptide that cross-reacted with antisera to the isoform purified from adult heart muscle. At about the time of birth, another 2.5-kb AMP deaminase transcript that encoded an 80-kDa peptide became detectable. This peptide cross-reacted with antisera to the predominant isoform purified from adult skeletal muscle.
