Abstract

Provided is a method of increasing 3,4,5,6-tetrakisphosphate by increasing the activity of inositol 1,3,4,5,6 pentakisphosphate 1-phosphatase, and a method of decreasing 3,4,5,6-tetrakisphosphate by decreasing the activity of inositol 1,3,4,5,6 pentakisphosphate 1-phosphatase. A method of reducing salt, fluid or mucous secretion in a subject, comprising increasing the activity of inositol 1,3,4,5,6 pentakisphosphate 1-phosphatase in the subject is provided. A method of treating a disease that is exacerbated by salt, fluid or mucous secretion is also provided, comprising increasing the activity of inositol 1,3,4,5,6 pentakisphosphate 1phosphatase in a subject having a disease that is exacerbated by mucous, whereby mucous secretion is reduced and the disease is treated.; Also provided is method of increasing salt and fluid secretion in a subject, comprising decreasing the activity of inositol 1,3,4,5,6 pentakisphosphate 1-phosphatase in the subject. A method of treating a disease that is treated by increased salt and fluid secretion is provided, comprising decreasing the activity of inositol 1,3,4,5,6 pentakisphosphate 1-phosphatase in a subject having a disease that is treated by increased salt and fluid secretion, whereby salt and fluid secretion is increased and the disease is treated.
