DESCRIPTION: RecName: Full=Coiled-coil alpha-helical rod protein 1; AltName: Full=Alpha-helical coiled-coil rod protein; AltName: Full=Putative gene 8 protein; Short=Pg8;
FUNCTION: May be a regulator of keratinocyte proliferation or differentiation.
TISSUE SPECIFICITY: Found in all tissues tested, abundantly expressed in heart, liver, skeletal muscle, kidney and pancreas, and to a lesser extent in lung and placenta. Overexpressed in keratinocytes of psoriatic lesions.
POLYMORPHISM: HCR*WWCC is associated with susceptibility to psoriasis. Psoriasis is a chronic inflammatory dermatosis that affects approximately 2% of the population. It is a multifactorial disease characterized by red, scaly skin lesions that are usually found on the scalp, elbows, and knees, and may be associated with severe arthritis. The lesions are caused by hyperproliferative keratinocytes and infiltration of inflammatory cells into the dermis and epidermis. The usual age of onset of psoriasis is between 15 and 30 years, although it can present at any age. Association of HCR with psoriasis seem to be due to linkage disequilibrium with Cw*06:02 (PubMed:11348465). HCR is unlikely to be directly involved in psoriasis development.

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.

ModBase Predicted Comparative 3D Structure on Q8TD31
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.
