This gene appears to be an evolving pseudogene of L-threonine 3-dehydrogenase (TDH). In both prokaryotes and eukaryotes, TDH catalyzes the first of two steps in one of two L-threonine degradation pathways. However, in human, the single gene with sequence similarity to TDH is not capable of encoding a functional TDH protein; the predicted protein lacks most of the C-terminus and parts of the NAD+ binding motif when compared to other species' TDH proteins. This suggests that the human gene is therefore a pseudogene. Transcripts of this gene are found in all tissues and alternatively spliced transcripts have been described. It is not known if these transcripts are translated, or if the possible protein product provides any functional role. [provided by RefSeq, Jul 2008]
[中文简述(自动翻译):]  该基??因似乎是L-苏氨酸3脱氢酶(TDH)发展迅速的假。在原核生物和真核生物中,TDH催化的第一个两L-苏氨酸降解途径之一两个步骤。然而,在人类,具有序列相似TDH的单基因不能够编码功能TDH蛋白质;相比于其他物种的TDH蛋白时所预测的蛋白质缺少最C-末端和对NAD的份离子结合基序。这表明,人类基因,因此是一个假基因。此基因的转录在所有组织中发现和可变剪接转录物已有描述。如果这些转录物被翻译它不知道,或者如果可能的蛋白产品提供任何功能性的作用。 [由RefSeq的,2008年7月提供]
