The gene clathrin assembly lymphoid myeloid leukemia (CALM or PICALM) is mapped to human chromosome 11q14. PICALM transcripts are ubiquitously expressed.
Synonyms: Anti-Clathrin assembly lymphoid myeloid leukemia protein; Anti-Phosphatidylinositol-binding clathrin assembly protein
Storage: -20C
Application: Anti-PICALM antibody produced in rabbit, a Prestige Antibody, is developed and validated by the Human Protein Atlas (HPA) project (www.proteinatlas.org). Each antibody is tested by immunohistochemistry against hundreds of normal and disease tissues. These images can be viewed on the Human Protein Atlas (HPA) site by clicking on the Image Gallery link. The antibodies are also tested using immunofluorescence and western blotting. To view these protocols and other useful information about Prestige Antibodies and the HPA, visit sigma.com/prestige.
Biochem Physiol Actions: Clathrin assembly lymphoid myeloid leukemia (CALM or PICALM) works as an endocytosis adaptor. It acts along with clathrin, adaptor ptotein-2 and PI(4,5)P2 (phosphatidylinositol 4,5-bisphosphate) in the initial stages of coated pit invagination at the membrane. It regulates size and maturation of clathrin coated vesicles. PICALM-AF10 (ALL1-fused gene from chromosome 10 protein) fusion protein is involved in t(10;11)(p13;q14) associated leukemogenesis. Polymorphism in PICALM is associated with Alzheimer's disease and influences the episodic memory performance in old age.
