上面语法的含义是,如果变量varname存在且不为空,则返回它的值,否则打印出varname: message,并中断脚本的执行。如果省略了message,则输出默认的信息“parameter null or not set.”。它的目的是防止变量未定义,比如${count:?"undefined!"}表示变量count未定义时就中断执行,抛出错误,返回给定的报错信息undefined!。 ...

However, Csk homodimerization and competition with PTPN22 in cells has not, to our knowledge, been investigated. Here we report that Csk self-association in Jurkat T cells can compete with PTPN22 for binding to the SH3 domain of Csk. Using structural analysis, we identified a histidine-to-...
