Description: Homo sapiens inositol polyphosphate-4-phosphatase, type I, 107kDa (INPP4A), transcript variant a, mRNA. RefSeq Summary (NM_004027): This gene encodes an Mg++ independent enzyme that hydrolyzes the 4-position phosphate from the inositol ring of phosphatidylinositol 3,4-bisphosphate, inositol 1,3,4-trisphosphate, and inositol 3,4-bisphosphate. Multiple transcript variants encoding distinct isoforms have been described. [provided by RefSeq, Aug 2008]. Transcript (Including UTRs) Position: hg19 chr2:99,061,321-99,207,496 Size: 146,176 Total Exon Count: 11 Strand: + Coding Region Position: hg19 chr2:99,136,512-99,204,071 Size: 67,560 Coding Exon Count: 9
ID:B8ZZB2_HUMAN DESCRIPTION: SubName: Full=Type I inositol 3,4-bisphosphate 4-phosphatase; CAUTION: The sequence shown here is derived from an Ensembl automatic analysis pipeline and should be considered as preliminary data.

We replicated asthma associations for a minority of candidate genes.
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.
