Purification of DNA ligases from mouse testis and their behavior during meiosis.

abstract：:CD9 and CD63 belong to a tetramembrane-spanning glycoprotein family called tetraspanin, and are involved in a wide variety of cellular processes, but the structure-function relationship of this family of proteins has yet to be clarified. CD9 associates with diphtheria toxin receptor (DTR), which is identical to the me...
