Application

N-Ethylmaleimide (NEM) has been used:
  • to prepare NEM-modified myosin beads
  • to block unmodified free thiols in samples
  • as a supplement in IP lysis/wash buffer for in vitro SUMOylation assay

Reagent for the covalent modification of cysteine residues in proteins.

Biochem/physiol Actions

Augments currents from native M-channels in sympathetic neurons and acts as an opener for KCNQ2, KCNQ4 and KCNQ5 channels.
Sulfhydryl alkylating agent that inactivates NADP-dependent isocitrate dehydrogenase and many endonucleases.

LGR5+ stem cells reside at crypt bottoms, intermingled with Paneth cells that provide Wnt, Notch and epidermal growth factor signals. Here we find that the related RNF43 and ZNRF3 transmembrane E3 ubiquitin ligases are uniquely expressed in LGR5+ stem cells.
