Igniting Ca 2+ sparks with TRPML1 [PDF]
Proceedings of the National Academy of Sciences, 2020 Storage and voiding of urine in mammals is accomplished by a reciprocal contractile relationship between the bladder and the urethra. During the storage phase, the urethra remains contracted to prevent leakage of urine, while the bladder is relaxed to accommodate the increased volume of urine.
