Abstract:
The present invention relates to proteins and polypeptides that (i) have the formula A-[W-A]where each A is independently a peptide of formula XXXXRXPXXXX where each X is independently any amino acid, R is arginine, and P is proline; each W is independently a linker; m is 1 or 2; and n is any number from 1 through 5; (ii) consist essentially of the formula XRXPXwhere each X is independently any amino acid, R is arginine, P is proline, n is any number from zero to fifteen, m is any number from zero to fifteen, and the sum of n and m is any number from eight to fifteen; (iii) have the formula A-Awhere each A is independently a peptide of formula XXXXRXPXXXX where each X is independently any amino acid, R is arginine, and P is proline; and n is any number from 1 through 5; or (iv) consist essentially of the formula XRXPXwhere each X is independently any amino acid, R is arginine, P is proline, n is any number from zero to seven, m is any number from zero to seven, and the sum of n and m is any number from zero to seven. Methods using these proteins and polypeptides to: identify the location of an RXP-binding domain of Cx43CT, modulate a Cx43 gap junction channel, screen for compounds that modulate Cx43CT, and measure Cx43CT-binding affinity of a compound that binds to Cx43CT, are also disclosed.
