Recombinant Human Tonsoku-like protein (TONSL), Truncated

Uniprot Id

Q96HA7

Target Species

Human

Target Name

TONSL

Target Full Name

Tonsoku-like protein

Target Function

Component of the MMS22L-TONSL complex, a complex that stimulates the recombination-dependent repair of stalled or collapsed replication forks. The MMS22L-TONSL complex is required to maintain genome integrity during DNA replication by promoting homologous recombination-mediated repair of replication fork-associated double-strand breaks. It may act by mediating the assembly of RAD51 filaments on ssDNA. Within the complex, may act as a scaffold.

Target Subcellular Location

Cytoplasm. Nucleus. Note=Mainly nuclear. Localizes to DNA damage sites, accumulates at stressed replication forks.

Target Protein Families

Tonsoku family

Target Tissue Specificity

Expressed in heart, skeletal muscle and tracheal epithelial cells.

Target Synonyms

Target Background

The protein encoded by this gene is thought to be a negative regulator of NF-kappa-B mediated transcription. The encoded protein may bind NF-kappa-B complexes and trap them in the cytoplasm, preventing them from entering the nucleus and interacting with the DNA. Phosphorylation of this protein targets it for degradation by the ubiquitination pathway, which frees the NF-kappa-B complexes to enter the nucleus.
