TPBG/5T4 Protein, Human (HEK293, His)

Customer Review

Based on 1 Customer Validation

TPBG/5T4 protein acts as an inhibitor of Wnt/β-catenin signaling, possibly by interacting indirectly with LRP6 and hindering Wnt3a-dependent LRP6 internalization. This means that TPBG/5T4 plays a crucial role in regulating the complex Wnt/β-catenin signaling pathway and exerts a regulatory influence on cellular responses related to this pathway. TPBG/5T4 Protein, Human (HEK293, His) is the recombinant human-derived TPBG/5T4 protein, expressed by HEK293 , with C-6*His labeled tag.

Biological Activity

Description

TPBG/5T4 protein acts as an inhibitor of Wnt/β-catenin signaling, possibly by interacting indirectly with LRP6 and hindering Wnt3a-dependent LRP6 internalization. This means that TPBG/5T4 plays a crucial role in regulating the complex Wnt/β-catenin signaling pathway and exerts a regulatory influence on cellular responses related to this pathway. TPBG/5T4 Protein, Human (HEK293, His) is the recombinant human-derived TPBG/5T4 protein, expressed by HEK293 , with C-6*His labeled tag.

Background

The TPBG/5T4 protein appears to serve as an inhibitor of Wnt/beta-catenin signaling, potentially achieved through indirect interaction with LRP6, thereby impeding Wnt3a-dependent LRP6 internalization. This implies a crucial role for TPBG/5T4 in modulating the intricate Wnt/beta-catenin signaling pathway, exerting regulatory influence on cellular responses associated with this pathway. Further exploration of the specific molecular mechanisms governing the interaction between TPBG/5T4 and LRP6, as well as its impact on Wnt3a-dependent LRP6 internalization, could yield valuable insights into the functional significance of TPBG/5T4 in shaping Wnt/beta-catenin signaling dynamics and its potential implications for various cellular processes.

Product Properties

Appearance

Lyophilized powder

Formulation

Lyophilized from a 0.2 μm filtered solution of PBS, pH 7.4.

Endotoxin Level

<1 EU/μg, determined by LAL method.

Reconstitution

It is not recommended to reconstitute to a concentration less than 100 μg/mL in ddH2O. For long term storage it is recommended to add a carrier protein (0.1% BSA, 5% HSA, 10% FBS or 5% Trehalose).

Storage & Stability

Stored at -20°C for 2 years from date of receipt. After reconstitution, it is stable at 4°C for 1 week or -20°C for longer (with carrier protein). It is recommended to freeze aliquots at -20°C or -80°C for extended storage.
