Recombinant Human E3 ubiquitin-protein ligase RNF6 (RNF6)

Uniprot Id

Q9Y252

Target Species

Human

Target Name

RNF6

Target Full Name

E3 ubiquitin-protein ligase RNF6

Target Function

E3 ubiquitin-protein ligase mediating 'Lys-48'-linked polyubiquitination of LIMK1 and its subsequent targeting to the proteasome for degradation. Negatively regulates axonal outgrowth through regulation of the LIMK1 turnover. Mediates 'Lys-6' and 'Lys-27'-linked polyubiquitination of AR/androgen receptor thereby modulating its transcriptional activity. May also bind DNA and function as a transcriptional regulator.

Target Involvement

Esophageal cancer (ESCR)

Target Subcellular Location

Nucleus. Cytoplasm. Cell projection, axon. Nucleus, PML body.

Target Protein Families

RNF12 family

Target Tissue Specificity

Weakly expressed in peripheral blood, spleen, prostate, testis and ovary. According to PubMed:18368307, it is preferentially expressed in testis and ovary and hardly detected in other tissues.

Target Synonyms

E3 ubiquitin-protein ligase RNF6; Ring finger protein (C3H2C3 type) 6; Ring finger protein 6; RING H2 protein; RING H2 protein RNF6; RNF 6; RNF6; RNF6_HUMAN; SPG2

Target Background

The protein encoded by this gene contains a RING-H2 finger motif. Deletions and mutations in this gene were detected in esophageal squamous cell carcinoma (ESCC), suggesting that this protein may be a potential tumor suppressor. Studies of the mouse counterpart suggested a role of this protein in the transcription regulation that controls germinal differentiation. Multiple alternatively spliced transcript variants encoding the same protein are observed.
