FUNCTION: [Summary is not available for the mouse gene. This summary is for the human ortholog.] This gene encodes a conserved serine/threonine kinase that is a member of the homeodomain-interacting protein kinase family. The encoded protein interacts with homeodomain transcription factors and many other transcription factors such as p53, and can function as both a corepressor and a coactivator depending on the transcription factor and its subcellular localization. Multiple transcript variants encoding different isoforms have been found for this gene. [provided by RefSeq, Nov 2011]
PHENOTYPE: Homozygous null mice display decreased apoptosis and increased neuron numbers in the trigeminal ganglion. [provided by MGI curators]

Protein Function and Prediction

Homeodomain interacting protein kinase 2 (Hipk2) is a conserved serine/threonine kinase that interacts with and phosphorylates homeodomain transcription factors to regulate transcription during development and in response to DNA damage (1). Hipk2 has a conserved N-terminal kinase domain with a DYRK motif, a nuclear localization sequence, a PEST domain, and C-terminal region that contains speckle-retention signal, an autoinhibitory domain, and a ubiquitylation site (1;2).

 

Northern blot analysis detected ubiquitous expression of a 11.0-kb HIPK2 transcript, with strongest expression in human neuronal tissue; a 7.8-kb transcript was detected in the uterus and a 1.4-kb transcript was detected in the pancreas (3). Hipk2 is detectable in postnatal day (P) 15 mouse embryos and is strong by P17 (4).  In situ hybridization detected expression in neural retina, telencephalon, and muscle at P16.5 (4). Similar to human HIPK2, mouse Hipk2 is ubiquitously expressed in the adult, Pierantoni et al. detected highest expression in the heart, muscle and kidney by RT-PCR (4).

 

Hipk2tm1Hko/tm1Hko; MGI:3624127

involves: C57BL/6

Embyronic fibroblasts from null mice are slightly resistant to UV radiation (5). Also, there are more frequent instances of neural tube defects in these mice (5).

 

Hipk2tm1Ejh/tm1Ejh; MGI:3487301

involves: 129X1/SvJ * C57BL/6

Homozygous mice exhibit diminished locomotor activity response to amphetamine compared with wild-type mice as well as abnormal limb grasping, impaired coordination, abnormal voluntary movement, and abnormal gait (6).  There is also decreased neuron apoptosis in dopaminergic neurons at E17.5 and P0 (6). Homozygotes have decreased dopaminergic neuron number throughout life (6).

 

Hipk2tm1Ejh/tm1Ejh; MGI:3487301

involves: 129X1/SvJ * C57BL/6J

In this genetic background, homozygotes have more neurons in the trigeminal ganglion at E13.5 and P0 due to a reduction in apoptotic neurons (7).

 

Hipk2tm1Afus/tm1Afus; MGI:4429497

involves: 129X1/SvJ * C57BL/6

Homozygotes in this model have abnormal motor capabilities/coordination/movement as well as an increase in the number of mouse embryonic fibroblasts in the G0/G1 phase of the cell cycle and reduced proliferation (8). Homozygotes have decreased birth and body weight over their life (8).
