    • The present invention relates to proteins and polypeptides that (i) have the formula A - [Wm - A]n 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 XnRXPXm where 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 - An 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; and n is any number from 1 through 5; or (iv) consist essentially of the formula XnRXPXm where 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.
    • 本发明涉及(i)具有式A - [Wm-A] n的蛋白质和多肽,其中每个A独立地是式XXXXRXPXXXX的肽,其中每个X独立地是任何氨基酸,R是精氨酸,P是脯氨酸 ; 每个W独立地是一个连接体; m为1或2; n是从1到5的任何数字; (ii)基本上由式XnRXPXm组成,其中每个X独立地是任何氨基酸,R是精氨酸,P是脯氨酸,n是从零到十五的任何数,m是从零到十五的任何数,以及n和 m是从8到15的任何数字; (iii)具有式A-An,其中每个A独立地是式XXXXRXPXXXX的肽,其中每个X独立地是任何氨基酸,R是精氨酸,P是脯氨酸; n是从1到5的任何数字; 或(iv)基本上由式XnRXPXm组成,其中每个X独立地是任何氨基酸,R是精氨酸,P是脯氨酸,n是从0到7的任何数字,m是从0到7的任何数字,并且n的总和 m是从零到七的任何数字。 使用这些蛋白质和多肽的方法:鉴定Cx43CT的RXP结合结构域的位置,调节Cx43间隙连接通道,筛选调节Cx43CT的化合物和测量与Cx43CT结合的化合物的Cx43CT结合亲和力,也是 披露。

    • The present invention relates to proteins and polypeptides that (i) have the formula A-[W-A] n where A is a peptide of formula XXXXRXPXXXX where X is any amino acid, R is arginine, and P is proline; W is a linker; and n is any number from 1 through 5; or (ii) consist essentially of the formula X n RXPX 3n where each X is 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 between ten and fifteen. Methods using these proteins and polypeptides to: screen for compounds that modulate Cx43CT, measure Cx43CT-binding affinity of a compound that binds to Cx43CT, and identify the location of an RXP-binding domain of Cx43CT, are also disclosed.
