项目摘要
This subproject is one of many research subprojects utilizing the
resources provided by a Center grant funded by NIH/NCRR. The subproject and
investigator (PI) may have received primary funding from another NIH source,
and thus could be represented in other CRISP entries. The institution listed is
for the Center, which is not necessarily the institution for the investigator.
Sequence analysis of ESTs and cDNA from trophoblast tissues of cattle, sheep and relatives. We also have a particular interest in gene families that have trophoblast-specific expression and that are evolving at high rates. These families include the interferon-tau, which are Type I interferon (IFN) structurally related to the IFN-alpha. Their genes are not virally inducible; instead they are constitutively expressed for a few days prior to implantation. A second family is the pregnancy- associated glycoproteins (PAG), which are structurally related to pepsin and other aspartic proteinases. There are over 100 members and they appear to be a new class of polypeptide-binding molecules, possibly involved in immune protection of the embryo. The third family is also large and consists of a group of polypeptides with Kunitz domains at their amino termini, preceded by a series of hydrophobic repeats, which exhibit overall general similarity but are nevertheless distinct in sequence.

牛、羊及其近缘种滋养层组织EST和cDNAs的序列分析。我们还对具有滋养层细胞特异性表达的基因家族特别感兴趣,这些基因家族正在以高速率进化。这些家族包括干扰素-tau,它是结构上与干扰素-α相关的I型干扰素(干扰素)。它们的基因不能通过病毒诱导;相反,它们在植入前几天进行结构性表达。第二个家族是妊娠相关糖蛋白(PAG),它在结构上与胃酶和其他天冬氨酸蛋白酶相关。有100多个成员,它们似乎是一类新的多肽结合分子,可能参与胚胎的免疫保护。第三个家族也很大,由一组多肽组成,在它们的氨基末端有kunitz域,前面有一系列疏水重复序列,它们总体上表现出总体上的相似性,但在序列上却是不同的。出版物--Winkelman,GL,Roberts,RM,Peterson,AJ,Alexenko,AP,和Ealy,AD.:“Ovine Interferon-Tau在围植入期胚胎中表达形式的鉴定:序列关系和比较生物学活动.”报告:61:1592-1600:1999。Hughes,AL,Green,JA,Garbayo JM,and Roberts,RM.:“最近复制的、位置上表达的基因大家族中的适应性多样化。”娜塔莉。阿卡德。科学编号:97:3319-3323:2000。成就-基于结构系统学对干扰素-tau的分类。
