Active Recombinant Human CSF1R(538-end) Protein, N-His-tagged

• Cat.No.: CSF1R-91H
• Product Overview: N-terminal 6Histagged, recombinant, human FMS, amino acids 538–end, expressed by baculovirus in Sf21 insect cells. Purified using Ni2+/NTAagarose.

Specification

• Description: CSF1R (colony stimulating factor I receptor), formerly known as FMS (McDonough feline sarcoma viral oncogene), is a receptor tyrosine kinase for CSF-1 and expressed primarily in monocytes, macrophages, and human tumor tissue. CSF-1 binding to FMS induces dimerization of the tyrosine kinase domain of the receptor, and stimulates the survival, proliferation, and differentiation of hematopoietic cells of the monocyte-macrophage series.
• Source: Sf21
• Species: Human
• Tag: His

Q&As

Are there any FDA-approved drugs targeting CSF1R for clinical use?

Yes, drugs like pexidartinib have been approved for the treatment of certain rare tumors called tenosynovial giant cell tumors (TGCT) that overexpress CSF1R.

How can CSF1R inhibitors impact the tumor microenvironment?

CSF1R inhibitors can modulate the tumor microenvironment by reducing the number of tumor-associated macrophages and promoting an anti-tumor immune response.

Can CSF1R inhibitors be used in combination with other cancer treatments?

Yes, CSF1R inhibitors are often used in combination with chemotherapy and immunotherapy to enhance treatment effectiveness.

What are the potential clinical applications of CSF1R inhibitors?

CSF1R inhibitors are being investigated for cancer therapy to block tumor-promoting macrophages and slow down cancer progression.

Can CSF1R inhibitors be used to treat neurodegenerative diseases?

Research is ongoing, and CSF1R inhibitors are being explored as a potential therapy for neurodegenerative diseases, but no FDA-approved treatments currently exist.
