KIAA0232
KIAA0232 is a nuclear phosphoserine protein which in humans is encoded by the KIAA0232 gene.
Gene
[edit]KIAA0232 is located at 4p16.1 neighboring TBC1 domain family member 14 and an uncharacterized locus. It has 10 exons which comprise its 4 known transcript variants.[1]
Expression
[edit]KIAA0232 is expressed fairly ubiquitously, but particularly highly in the brain relative to other tissues according to GEO normal tissue expression profiling.[2] Other notable areas of high expression identified by EST profiling include nerves, umbilical cord, and parathyroid.[3]
Homology
[edit]Paralogs
[edit]There are no known paralogs of KIAA0232.
Orthologs
[edit]KIAA0232 is conserved in most animals, including mammals, reptiles, birds, amphibians, insects, and as far back as Trichnella spiralis, a species of nematode. It is not found in fungi, plants, or prokaryotes.[4]
Protein
[edit]The KIAA0232 protein is 1395 amino acids in length with a molecular weight of 154.8kDa. It has higher than average frequencies of serine and glutamic acid residues as well as several multi-serine runs that are evolutionarily conserved. It has an isoelectric point of 4.52.[5][6]
Domains
[edit]KIAA0232 is largely composed of DUF4603.[7]
Subcellular localization
[edit]KIAA0232 is predicted to have nuclear localization.[5]
Post-translational modification
[edit]KIAA0232 is predicted by the tools at ExPASy to be highly phosphorylated, with 15 tyrosine specific sites, 25 threonine specific sites, and 103 serine specific sites.[8]
Interacting proteins
[edit]KIAA0232 is experimentally known to interact with YWHAZ,[9] DYRK1A, and DYRK1B.[10] via two hybrid interaction experiments. YWHAZ is an apoptotic path regulator known to bind to phosphoserine proteins. DYRK1A/B are dual-specificity tyrosine kinases. This corroborates the post-translational modification predictions.
