RNF12 X-Linked Intellectual Disability Mutations Disrupt E3 Ligase Activity and Neural Differentiation [PDF]
Summary: X-linked intellectual disability (XLID) is a heterogeneous syndrome affecting mainly males. Human genetics has identified >100 XLID genes, although the molecular and developmental mechanisms underpinning this disorder remain unclear.

Role of Nse1 Subunit of SMC5/6 Complex as a Ubiquitin Ligase
Structural Maintenance of Chromosomes (SMC) complexes are important for many aspects of the chromosomal organization. Unlike cohesin and condensin, the SMC5/6 complex contains a variant RING domain carried by its Nse1 subunit.

Tag Team Ubiquitin Ligases [PDF]
Cullin-RING (CRL) and RING1-IBR-RING2 (RBR) are two distinct types of ubiquitin ligases. In this issue, Scott et al. show that CRLs activate the RBR enzyme ARIH1 to initiate ubiquitin chains on CRL substrates, thereby marking an unexpected and important advance in our understanding of both enzymes.

A Ubiquitin-like Protein Unleashes Ubiquitin Ligases [PDF]
Modification of cullin-RING ubiquitin ligases by the ubiquitin-like molecule Nedd8 promotes substrate ubiquitination. A crystal structure of a cullin modified by Nedd8 recently reported in Cell (Duda et al., 2008) and a biochemical study in Molecular Cell (Saha and Deshaies, 2008) reveal the dramatic impact on the ligase machinery by conjugation of ...

G3BP1 modulates SPOP to promote prostate tumorigenesis
Speckle-type POZ protein (SPOP), a Cullin 3-based ubiquitin ligase (CUL3SPOP), acts as a prostate-specific tumor suppressor. Loss-of-function mutations in SPOP occur in 10% of primary prostate cancer with a high Gleason grade and poor prognosis. However,

Cbl-c ubiquitin ligase activity is increased via the interaction of its RING finger domain with a LIM domain of the paxillin homolog, Hic 5. [PDF]
Cbl proteins (Cbl, Cbl-b and Cbl-c) are ubiquitin ligases that are critical regulators of tyrosine kinase signaling. In this study we identify a new Cbl-c interacting protein, Hydrogen peroxide Induced Construct 5 (Hic-5).
