Recombinant Human E3 ubiquitin-protein ligase Hakai (CBLL1)

Uniprot Id

Q75N03

Target Species

Human

Target Name

CBLL1

Target Full Name

E3 ubiquitin-protein ligase Hakai

Target Function

E3 ubiquitin-protein ligase that mediates ubiquitination of several tyrosine-phosphorylated Src substrates, including CDH1, CTTN and DOK1. Targets CDH1 for endocytosis and degradation. Associated component of the WMM complex, a complex that mediates N6-methyladenosine (m6A) methylation of RNAs, a modification that plays a role in the efficiency of mRNA splicing and RNA processing. Its function in the WMM complex is unknown.

Target Subcellular Location

Nucleus speckle. Nucleus, nucleoplasm. Cytoplasm.

Target Background

This gene encodes an E3 ubiquitin-ligase for the E-cadherin complex and mediates its ubiquitination, endocytosis, and degradation in the lysosomes. The encoded protein contains a RING-finger domain and is also thought to have a role in control of cell proliferation. A related pseudogene has been identified on chromosome X. Alternative splicing results in a non-coding transcript variant.
