Function
COR1A_MOUSE May be a crucial component of the cytoskeleton of highly motile cells, functioning both in the invagination of large pieces of plasma membrane, as well as in forming protrusions of the plasma membrane involved in cell locomotion. In mycobacteria-infected cells, its retention on the phagosomal membrane prevents fusion between phagosomes and lysosomes.[1]
Publication Abstract from PubMed
In recent years, short coiled coils have been used for applications ranging from biomaterial to medical sciences. For many of these applications knowledge of the factors that control the topology of the engineered protein systems is essential. Here, we demonstrate that trimerization of short coiled coils is determined by a distinct structural motif that encompasses specific networks of surface salt bridges and optimal hydrophobic packing interactions. The motif is conserved among intracellular, extracellular, viral, and synthetic proteins and defines a universal molecular determinant for trimer formation of short coiled coils. In addition to being of particular interest for the biotechnological production of candidate therapeutic proteins, these findings may be of interest for viral drug development strategies.
