Application notes
ICC/IF: Use at a concentration of 1 - 2 µg/ml.
IP: 10-20 ug of the antibody can immunoprecipitate EB1 from a cell lysate of HeLa cells.
WB: Use at a concentration of 0.5 - 1 µg/ml. Predicted molecular weight: 30 kDa. Staining of the EB1 band in immunoblotting is specifically inhibited with the immunizing peptide.
Not yet tested in other applications.
Optimal dilutions/concentrations should be determined by the end user.

Target
-
Function
May be involved in microtubule polymerization, and spindle function by stabilizing microtubules and anchoring them at centrosomes. May play a role in cell migration. -
Tissue specificity
Ubiquitously expressed. -
Sequence similarities
Belongs to the MAPRE family.
Contains 1 CH (calponin-homology) domain.
Contains 1 EB1 C-terminal domain. -
Domain
Composed of two functionally independent domains. The N-terminal domain forms an hydrophobic cleft involved in microtubule binding and the C-terminal is involved in the formation of mutually exclusive complexes with APC and DCTN1. -
Cellular localization
Cytoplasm > cytoskeleton. Cytoplasm > cytoskeleton > centrosome. Associated with the microtubule network at the growing distal tip of microtubules. Also enriched at the centrosome. - Information by UniProt
