ID:PLCD1_HUMAN DESCRIPTION: RecName: Full=1-phosphatidylinositol 4,5-bisphosphate phosphodiesterase delta-1; EC=3.1.4.11; AltName: Full=Phosphoinositide phospholipase C-delta-1; AltName: Full=Phospholipase C-III; Short=PLC-III; AltName: Full=Phospholipase C-delta-1; Short=PLC-delta-1; FUNCTION: The production of the second messenger molecules diacylglycerol (DAG) and inositol 1,4,5-trisphosphate (IP3) is mediated by activated phosphatidylinositol-specific phospholipase C enzymes. Essential for trophoblast and placental development. CATALYTIC ACTIVITY: 1-phosphatidyl-1D-myo-inositol 4,5- bisphosphate + H(2)O = 1D-myo-inositol 1,4,5-trisphosphate + diacylglycerol. COFACTOR: Binds 3 calcium ions per subunit. Two of the calcium ions are bound to the C2 domain (By similarity). DISEASE: Defects in PLCD1 are the cause of nail disorder non- syndromic congenital type 3 (NDNC3) [MIM:151600]. NDNC3 is a nail disorder characterized by a white appearance of the nail plate (true leukonychia), the nail bed (pseudoleukonychia), or neither (apparent leukonychia). Leukonychia may involve all of the nail (leukonychia totalis) or only part of the nail (leukonychia partialis), or can appear as one or more transverse bands (leukonychia striata) or white spots (leukonychia punctata). SIMILARITY: Contains 1 C2 domain. SIMILARITY: Contains 2 EF-hand domains. SIMILARITY: Contains 1 PH domain. SIMILARITY: Contains 1 PI-PLC X-box domain. SIMILARITY: Contains 1 PI-PLC Y-box domain.
The RNAfold program from the Vienna RNA Package is used to perform the secondary structure predictions and folding calculations. The estimated folding energy is in kcal/mol. The more negative the energy, the more secondary structure the RNA is likely to have.

The pictures above may be empty if there is no ModBase structure for the protein. The ModBase structure frequently covers just a fragment of the protein. You may be asked to log onto ModBase the first time you click on the pictures. It is simplest after logging in to just click on the picture again to get to the specific info on that model.
Orthologous Genes in Other Species
Orthologies between human, mouse, and rat are computed by taking the best BLASTP hit, and filtering out non-syntenic hits. For more distant species reciprocal-best BLASTP hits are used. Note that the absence of an ortholog in the table below may reflect incomplete annotations in the other species rather than a true absence of the orthologous gene.
