Recombinant Human CD44 Protein, MYC/DDK-tagged

• Cat.No.: CD44-3096H
• Product Overview: Recombinant Human CD44 protein, fused to MYC/DDK-tagged at C-terminus, was expressed in HEK293.

Specification

• Description: The protein encoded by this gene is a cell-surface glycoprotein involved in cell-cell interactions, cell adhesion and migration. It is a receptor for hyaluronic acid (HA) and can also interact with other ligands, such as osteopontin, collagens, and matrix metalloproteinases (MMPs). This protein participates in a wide variety of cellular functions including lymphocyte activation, recirculation and homing, hematopoiesis, and tumor metastasis. Transcripts for this gene undergo complex alternative splicing that results in many functionally distinct isoforms, however, the full length nature of some of these variants has not been determined. Alternative splicing is the basis for the structural and functional diversity of this protein, and may be related to tumor metastasis.

Q&As

What is the role of CD44 in cancer?

CD44 is implicated in cancer progression and metastasis. It promotes tumor cell invasion, migration, and adhesion to the extracellular matrix. CD44 also plays a role in cancer stem cell maintenance and drug resistance. Its overexpression is associated with poor prognosis in various types of cancer.

Can CD44 be targeted for therapeutic purposes?

Targeting CD44 has been explored as a potential therapeutic strategy in cancer and inflammatory diseases. Strategies include blocking CD44-ligand interactions, inhibiting CD44 signaling pathways, and targeting CD44-positive cancer stem cells. However, further research is needed to fully understand the complex roles of CD44 in different disease contexts and to develop effective CD44-targeted therapies.

How is the expression of CD44 regulated?

The expression of CD44 is regulated at multiple levels, including transcriptional control, alternative splicing, and post-translational modifications. Transcription factors such as Sp1 and NF-κB can bind to the CD44 promoter region to regulate its gene expression. Additionally, alternative splicing of CD44 pre-mRNA generates CD44 isoforms with different functions and expression patterns.

How does CD44 contribute to immune regulation?

CD44 is involved in immune cell activation, trafficking, and homing. It participates in the recruitment of leukocytes to sites of inflammation and mediates T cell adhesion and migration. CD44 can also modulate immune responses by interacting with other immune receptors and cytokines, and it is involved in the regulation of T cell activation and differentiation.

How is CD44 involved in immune regulation?

CD44 plays a vital role in immune regulation by participating in immune cell activation, migration, and modulation of T-cell activation and differentiation. CD44 is expressed on various immune cell populations, including T cells, B cells, natural killer cells, and dendritic cells. It serves as an adhesion molecule and facilitates immune cell trafficking to lymphoid tissues and inflammatory sites. CD44 also functions as a co-stimulatory receptor, enhancing T-cell activation and cytokine production upon interaction with its ligands. Moreover, CD44 isoforms have been implicated in the differentiation of T helper cell subsets, such as Th1, Th2, and Th17 cells. These findings highlight the multifaceted role of CD44 in immune regulation and its potential as a therapeutic target for immune-related disorders.

What is the cellular localization of the protein CD44?

CD44 is a transmembrane glycoprotein predominantly localized on the cell surface, specifically in the plasma membrane of various cell types, including epithelial cells, leukocytes, and mesenchymal cells.

What are the signaling pathways associated with CD44?

CD44 can activate various signaling pathways, including PI3K/AKT, MAPK/ERK, and NF-κB pathways. These pathways mediate downstream cellular processes such as cell survival, proliferation, migration, and immune responses. CD44 can also interact with other cell surface receptors, such as receptor tyrosine kinases, to modulate their signaling activities.
