We have systematically measured KD (the equilibrium dissociation constant between the antibody and its antigen), of more than 840 recombinant antibodies to assess not only their individual KD values but also to see the average affinity of antibody. Based on the comparison with published literature values for mouse monoclonal antibodies, Recombinant antibodies appear to be on average 1-2 order of magnitude higher affinity.

Supplementary information

Lymphocyte-specific protein 1 also known as LSP1 is a 52 kDa intracellular F-actin binding protein. It plays a role in cytoskeletal organization and cell motility. This protein has significant expression in lymphocytes neutrophils macrophages and endothelial cells. LSP1 modulates several cellular functions including adhesion and migration by interacting with the actin cytoskeleton. Known alternatively as pp52 and WD-40 repeat-containing protein 1 LSP1 acts as a link connecting signal transduction from cell surface receptors to cytoskeletal regions.
Biological function summary

LSP1 influences immune cell regulation and inflammatory response. By acting as an important player in the modulation of actin polymerization it contributes to leukocyte chemotaxis and transmigration. LSP1 forms part of a larger protein complex involved in reorganizing the cytoskeleton facilitating cellular dynamics necessary for immune response. Additionally interactions with adapter proteins like 14-3-3 add another level of functional regulation.

Pathways

LSP1 integrates into the chemokine signaling pathway and the P38 MAPK signaling pathway. In these pathways it exerts influence on cellular processes such as migration and response to external stimuli. It shows connections with proteins such as CXCR4 and MAPK highlighting its role in conveying chemotactic signals that direct immune cells toward inflammatory sites. These interactions are integral in establishing directionality and speed of cell movement in response to chemokine gradients.

Aberrations in LSP1 function or expression link to autoimmune conditions like systemic lupus erythematosus and vascular disorders like atherosclerosis. Its role in mediating vascular permeability and leukocyte migration suggests that dysregulation can contribute to pathogenic inflammation. Related proteins like MCP-1 and ICAM-1 participate in these disease pathways highlighting the involvement of LSP1 in modulating endothelial responses and immune cell recruitment at sites of inflammation.
