Gene

edit

The Human CCHCR1 gene is located at 6p21.33. It is also known as Coiled-Coil Alphahelical Rod Protein 1, C6orf18, Putative Gene 8 Protein, SBP, HCR (A-Helix Coiled-Coil Rod Homologue), pg8, StAR-Binding Protein, and Pg8.

Structure

edit

The structure of CCHCR1 is primarily composed of alpha-helices, coils[clarification needed], and a small amount of beta sheets, according to PELE.[8]

Expression

edit

Function

edit

May be a regulator of keratinocyte proliferation or differentiation.

Interacting Proteins

edit

CCHCR1 has been shown to interact with POLR2C,[9] KRT17 ,[10] TOP3B,[11] Steroidogenic acute regulatory protein,[10] TRAF4,[12] HLA-C,[13] TCF19,[13] SNX29,[14] EEF1D,[15] and EEF1B2.[15]

Clinical significance

edit

In genetically engineered mice, certain CCHCR1 polymorphisms cause upregulation of the expression of cytokeratins 6 (KRT6A), 16 (KRT16) and 17 (KRT17) and change in expression in other genes associated with terminal differentiation and formation of the cornified cell envelope. These CCHCR1 polymorphisms may therefore be associated with a susceptibility to psoriasis.[16] Defective functioning of CCHCR1 may lead to abnormal keratinocyte proliferation which is a key feature of psoriasis.[17]

CCHCR1 polymorphisms have also been found to be associated with multiple sclerosis.[18]
