Description

General description

Tsg101-associated ligase (TAL), contains an N-terminal leucine-rich repeat (LRR), followed by an ezrin-radixin-moesin (ERM) domain, a coiled-coil (CC) region, a sterile alpha motif (SAM) domain and a C-terminal C3HC4-type RING finger domain. Also called leucine-rich repeat and sterile alpha motif-containing protein 1 (LRSAM1), TAL is an E3 ubiquitin ligase. TAL gene is mapped to human chromosome 9.

Specificity

Anti-Tal (CS-15) recognizes human, dog, rat, and mouse Tal (84 kDa, may appear as doublet).

Immunogen

synthetic peptide encoding amino acids 709-723 located near the C-terminus of human Tal, conjugated to KLH. This sequence is highly conserved in mouse and rat Tal (two amino acids substitution).

Application

Anti-Tal (CS-15) antibody produced in rabbit may be used in immunoblotting and immunoprecipitation.

Biochem/physiol Actions

Tsg101-associated ligase (TAL) plays a key role in cell signaling, cell adhesion and regulates cargo sorting. Reduced expression of Tsg101 shunts active epidermal growth factor receptor (EGFRs) from the normal degradative pathway to a recycling route. Tal, which interacts with Tsg101 associates with and ubiquitylates Tsg101 in a manner that regulates receptor trafficking and budding of viral particles. Tal binds to Tsg101 in a bimodal mode, through an interaction of its CC domain with the steadiness box (SB) of Tsg101, and also via binding of the UEV domain of Tsg101 with two PTAP motifs just upstream of the C-terminal RING domain. Tal interaction with Tsg101 promotes multiple monoubiquitination of Tsg101, rather than polyubiquitination, which leads to the release of Tsg101 from membrane complexes and its inactivation. Mutations in the TAL gene is implicated in Charcot-Marie-Tooth (CMT) syndrome.

Physical form

Solution in 0.01 M phosphate buffered saline, pH 7.4, containing 15 mM sodium azide.

Storage and Stability

For continuous use, store at 2-8 °C for up to one month. For extended storage, freeze in working aliquots. Repeated freezing and thawing is not recommended. Storage in frost-free freezers is also not recommended. If slight turbidity occurs upon prolonged storage, clarify the solution by centrifugation before use. Working dilutions should be discarded if not used within 12 hours.
