This entry represents a block of three HEAT repeats found at the N-terminal of elongation factor 3 (EF3) from yeast, after the 5 HEAT repeats block [1]. EF3 is a ribosome-dependent ATPase that functions in cytoplasmic translation elongation. It is required for the ATP-dependent release of deacylated tRNA from the ribosomal E-site during protein biosynthesis [1,2]. This block is also found in stalled ribosome sensor GCN1, a ribosome collision sensor that plays a key role in the RNF14-RNF25 translation quality control pathway, a pathway that takes place when a ribosome has stalled during translation, and which promotes ubiquitination and degradation of translation factors on stalled ribosomes [3].

ABC transporters for a large family of proteins responsible for translocation of a variety of compounds across biological membranes. ABC transporters are the largest family of proteins in many completely sequenced bacteria. ABC transporters are composed of two copies of this domain and two copies of a transmembrane domain Pfam:PF00664. These four domains may belong to a single polypeptide as in Swiss:P13569, or belong in different polypeptide chains.	Domain
