Survival and growth of C57BL/6J mice lacking the BK channel, : lower adult body weight occurs together with higher body fat.

Big conductance potassium (BK) channels contribute to K flow and electrical behavior in many cell types. Mice made null for the gene () producing the BK channel (BK) exhibit numerous deficits in physiological functions. Breeding mice lacking a single allele of (C57BL/6J background) had litter sizes of approximately eight pups.
