The core of therapeutic interest lies in the CBD3 peptide itself, a 15-amino acid sequence identified as the calcium-binding domain 3 of CRMP-2. Its ability to interfere with calcium channel function is central to its analgesic properties.Myr-tat-CBD3 | Myr-YGRKKRRQRRRARSRLAELRGVPRGL However, to enhance its delivery and efficacy, various modified versions have been developed.
One notable derivative is TAT-CBD3, which incorporates the TAT cell-penetrating motif from the HIV-1 proteinInhibition of autophagy by CRMP2-derived peptide ST2-104 .... This fusion allows the peptide to more effectively cross cell membranes and reach its intracellular targets, leading to sustained relief of neuropathic pain in animal models. Other modifications, such as N-terminal myristoylation (Myr-tat-CBD3), aim to improve membrane tethering and localization near the calcium channels, further enhancing its therapeutic potential.TAT-CBD3，一种来自CRMP2 的15 个氨基酸肽，与HIV-1 蛋白的TAT 细胞穿透序列融合，破坏CRMP2-NMDAR 相互作用，而不改变NMDAR 定位。- 高纯度，全球文献引用。
