Characterization of a full-length cDNA encoding a bovine four tandem-repeat ubiquitin

Abstract:
Screening of a bovine seminal vesicle cDNA library in lambda gt11 with monospecific anti-ubiquitin IgGs yielded two independent clones pUF4AA and pUD4AA. Sequence analysis of pUF4AA revealed a coding region for a polyubiquitin with four tandem-repeats. We observed a replacement of serine (133) by phenylalanine in the second ubiquitin repeat. The deduced amino acid sequence of pUD4AA, however, possessed the typical serine (133) residue. This serine-phenylalanine replacement could result from allelic polymorphism.

RNA is the Missing Link Between DNA and Proteins
In the early 1900s, scientists discovered that DNA stores all the information needed for cellular functions and that proteins perform most of these functions. However, the mechanisms of converting genetic information into functional proteins remained unknown for many years. Initially, it was believed that a single gene is...
