METHOD FOR SCREENING A MODULATOR OF A TMEM16 FAMILY MEMBER |
摘要 |
The present invention relates to a method for screening a modulator of a TMEM16 family member, which comprises the following steps:
(1) treating cells expressing the TMEM16 family member with a candidate of the modulator, and(2) determining whether the candidate alters distribution of a lipid selected from phosphatidylserine, phosphatidylcholine, and galactosylceramide in plasma membrane of the cells,
wherein a candidate which increases distribution of phosphatidylserine in the outer leaflet of plasma membrane compared to control is selected as a modulator enhancing a function of the TMEM16 family member, and a candidate which decreases distribution of phosphatidylserine in the outer leaflet of plasma membrane compared to control is selected as a modulator suppressing a function of the TMEM16 family member, and
a candidate which increases distribution of phosphatidylcholine or galactosylceramide in the inner leaflet of plasma membrane compared to control is selected as a modulator enhancing a function of the TMEM16 family member, and a candidate which decreases distribution of phosphatidylcholine or galactosylceramide in the inner leaflet of plasma membrane compared to control is selected as a modulator suppressing a function of the TMEM16 family member. |
