DATASHEET  

Coronins are highly-conserved F-actin binding proteins that play important roles in lamellipodial protrusion during various types of cell motility. In yeast, coronins regulate cytoskeletal changes through inhibition of Arp2/3 complex. Human coronins have been classified in three subgroups type I (coronin-1A, -1B, -1C), type II (coronin-2A, -2B), and type III (coronin-7). These coronins have at least one large b-propeller region that mediates protein-protein interactions and type I and II coronins have coiled-coil regions involved in oligiomerization. Coronin-1B is ubiquitously expressed and localizes to the leading edge of cell protrusions in migrating fibroblasts. Both Coronin-1B and Coronin-1A interaction with Arp2/3 complex may be regulated by phosphorylation. PKC phosphorylates the N-terminus at Ser-2 , and this phosphorylation reduces interactions with Arp2/3 leading to diminshed cell motility.

Coronin-1B (C-terminus) synthetic peptide corresponds to amino acids at the C-terminus of human coronin-1B. This sequence has high homology to the conserved site in rat and mouse coronin-1B, and less than 50% homology to similar regions in other coronins.

This peptide is specifically recognized by Coronin-1B (C-terminus) antibody (CP2581) in ELISA, and has been shown to block the reactivity of CP2581 in Western blot and is recommended for blocking in immunocytochemistry.

*All molecular weights (MW) are confirmed by comparison to Bio-Rad Rainbow Markers and to western blot mobilities of known proteins with similar MW.
