What Is LATS1 and Why Is It Important in Research?

LATS1 (Large Tumor Suppressor Kinase 1) is a serine/threonine kinase and a core effector of the Hippo signaling pathway, a highly conserved pathway that regulates organ size, cell proliferation, and apoptosis. LATS1 phosphorylates and inactivates the transcriptional co-activators YAP (Yes-Associated Protein) and TAZ, promoting their cytoplasmic retention and proteasomal degradation. Dysregulation of LATS1 activity has been implicated in a broad range of human cancers, making it a critical target in oncology research. Recombinant Human LATS1 Protein (rp371987) enables researchers to study these mechanisms in vitro with a well-defined, human-derived reagent.

How Should Recombinant Human LATS1 Protein Be Stored and Handled?

Proper storage and handling of Recombinant Human LATS1 Protein are critical to maintaining its activity and integrity. General best practices for recombinant kinase proteins include:

  • Storage temperature: Store at -80°C for long-term preservation. Short-term storage at -20°C may be acceptable depending on formulation; refer to the product datasheet for confirmed conditions.
  • Avoid freeze-thaw cycles: Repeated freezing and thawing can cause protein aggregation and loss of kinase activity. Aliquot the protein upon first use to minimize freeze-thaw events.
  • Reconstitution: If supplied lyophilized, reconstitute with the recommended buffer (typically sterile water or PBS containing a carrier protein such as BSA) as specified in the datasheet.
  • Working solutions: Prepare working dilutions fresh and keep on ice during experiments to preserve enzyme activity.
  • Contamination prevention: Use sterile, low-binding tubes and pipette tips to prevent adsorption and microbial contamination.

Always refer to the official product datasheet for product-specific storage and handling instructions.

What Quality and Purity Standards Apply to This Recombinant Protein?

Recombinant Human LATS1 Protein (rp371987) is manufactured to research-grade quality standards. Key quality attributes for recombinant proteins of this class typically include:

  • Purity: Assessed by SDS-PAGE and/or HPLC; research-grade recombinant proteins are commonly supplied at >85–95% purity. Confirm the specific purity specification in the product datasheet.
  • Biological activity: Verified by functional kinase assay (e.g., phosphorylation of a validated substrate such as YAP or a peptide analog).
  • Endotoxin levels: Tested and controlled to minimize interference with cell-based assays; specific endotoxin limits are listed on the datasheet.
  • Identity confirmation: Confirmed by mass spectrometry or N-terminal sequencing to verify the correct human LATS1 sequence.

For lot-specific quality data including purity, activity, and endotoxin results, please request the Certificate of Analysis (CoA) for your specific lot number from Aladdin Scientific.

Frequently asked questions

What is the biological function of LATS1 and how does it relate to cancer research?

LATS1 is a serine/threonine kinase that acts as a central node in the Hippo tumor suppressor pathway. It phosphorylates YAP and TAZ, preventing their nuclear translocation and thereby inhibiting transcription of pro-proliferative genes. Loss of LATS1 function leads to unchecked YAP/TAZ activity, which has been associated with tumor development, metastasis, and drug resistance in multiple cancer types.

Is Recombinant Human LATS1 Protein (rp371987) suitable for use in kinase inhibitor screening assays?

Yes, recombinant LATS1 protein is commonly used in in vitro kinase assays to profile and rank small-molecule inhibitors by their ability to suppress LATS1 kinase activity toward validated substrates. Researchers should optimize assay conditions including protein concentration, substrate concentration, ATP concentration, and buffer composition using the product datasheet as a starting point. Confirmation of activity in the specific assay format used in your laboratory is recommended before initiating a screening campaign.

How do I request a Certificate of Analysis (CoA) or Safety Data Sheet (SDS) for rp371987?

Certificates of Analysis and Safety Data Sheets for Recombinant Human LATS1 Protein (rp371987) are available through Aladdin Scientific. You can request these documents directly from the product page on the Aladdin Scientific website or by contacting the customer service team with your lot number. Providing the lot number ensures you receive documentation specific to the exact batch of protein you received.

What expression system is used to produce Recombinant Human LATS1 Protein?

The expression system used for Recombinant Human LATS1 Protein (rp371987) should be confirmed by consulting the official product datasheet, as expression host details (e.g., E. coli, insect cells, HEK293 mammalian cells) directly affect post-translational modifications and kinase activity. For a kinase such as LATS1, mammalian or baculovirus-insect cell expression systems are commonly employed to support proper folding and relevant phosphorylation. Contact Aladdin Scientific for confirmation of the specific expression system used for this product.

Can this protein be used for co-immunoprecipitation (co-IP) or pull-down experiments?

Recombinant Human LATS1 Protein may be suitable as bait or prey protein in pull-down or co-immunoprecipitation experiments to study protein-protein interactions within the Hippo pathway, such as interactions with MOB1, MST1/2, or 14-3-3 proteins. However, suitability for co-IP should be empirically validated in your experimental system, as buffer conditions, tag configurations, and binding partner concentrations can significantly affect results. Refer to the product datasheet for any confirmed interaction data.
