Inactivating current
WebApr 15, 2001 · The CTX-sensitive current had a rapid, transiently decaying component, with a time constant of inactivation of 50 ± 7 msec (n = 8), which presumably flowed through maxi-K Ca 2+-dependent K + channels, and a non-inactivating current, which may have been attributable to other delayed-rectifying K + channels that were blocked by CTX (Fig.7Bii). WebNov 26, 2024 · Ribosome-inactivating proteins (RIPs) are highly potent protein toxins which restrain protein synthesis by directly targeting the ribosomes [].Plant-derived RIPs can be classified into two main types: (1) a polypeptide chain of about 30 kDa (Type I) and (2) a more toxic heterodimer composed of an A chain which has identical function to the Type I …
