Copine C plays a role in adhesion and streaming in .

Copines are a family of calcium-dependent membrane-binding proteins. To study these proteins, anull mutant for was created in , which has six copines genes (). During development, cells were able to aggregate, but did not form streams.

Copine A Interacts with Actin Filaments and Plays a Role in Chemotaxis and Adhesion.

Copines make up a family of calcium-dependent, phospholipid-binding proteins found in numerous eukaryotic organisms. Copine proteins consist of two C2 domains at the N-terminus followed by an A domain similar to the von Willebrand A domain found in integrins. We are studying copine protein function in the model organism, , which has six copine genes, .

Cyclic AMP signaling in Dictyostelium promotes the translocation of the copine family of calcium-binding proteins to the plasma membrane.

Background: Copines are calcium-dependent phospholipid-binding proteins found in many eukaryotic organisms and are thought to be involved in signaling pathways that regulate a wide variety of cellular processes. Copines are characterized by having two C2 domains at the N-terminus accompanied by an A domain at the C-terminus. Six copine genes have been identified in the Dictyostelium genome, cpnA - cpnF.
