The present invention relates to the provision of a pharmaceutical composition comprising a nucleic acid molecule encoding a alkylglycerol monooxygenase (TMEM195 glyceryl ether monooxygenase EC 1.14.16.5). The present invention also provides for a method for producing said alkylglycerol monooxygenase (TMEM195 glyceryl ether monooxygenase EC 1.14.16.5) polypeptides encoded by said polynucleotides. Moreover, the use of such polypeptides as well as of antagonists/inhibitors of such polypeptides in a medical setting (e.g. in from of a pharmaceutical composition) and methods for assessing the activity of a candidate molecule suspected of being an antagonist/inhibitor or agonist/activator in order to identify potential antagonists/inhibitors or agonists/activators of the polypeptide are also provided in the present invention. Finally, the present invention provides kits for carrying out said methods wherein the kits comprise polynucleotides and/or antibodies capable of detecting the activity of alkylglycerol monooxygenase.
