Abstract
At the primary level small heat shock proteins are commonly described as a conserved α-crystallin domain flanked by regions that have disparate sequence content. While this holds true when analysing simple pairwise alignments, it belittles the importance of these N-terminal and C-terminal extensions. Careful examination of their sequences, combined with an improved understanding of the structure and activity of these proteins, yields an alternative view where the N- and C-terminal arms play an important role in function. In this chapter we shall describe the current understanding of these two regions and highlight that they both demonstrate structural and functional properties that are highly conserved across all kingdoms of life.
