InnateDB Gene

IDBG-50125 (DPP6)

Protein Structure

UniProt Annotation

Function

May be involved in the physiological processes of brain function. Has no dipeptidyl aminopeptidase activity. May modulate the cell surface expression and the activity of the potassium channel KCND2. {ECO:0000269PubMed:15476821}.

Subcellular Localization

Membrane {ECO:0000305}; Single-pass type II membrane protein {ECO:0000305}.

Disease Associations

Familial paroxysmal ventricular fibrillation 2 (VF2) [MIM:612956]: A cardiac arrhythmia marked by fibrillary contractions of the ventricular muscle due to rapid repetitive excitation of myocardial fibers without coordinated contraction of the ventricle and by absence of atrial activity. {ECO:0000269PubMed:19285295}. Note=The disease is caused by mutations affecting the gene represented in this entry. A genetic variation 340 bases upstream from the ATG start site of the DPP6 gene is the cause of familial paroxysmal ventricular fibrillation type 2.

Tissue Specificity

Expressed predominantly in brain.
