Transcription 5564 bp mRNA


Description 1640 amino acids, 187 kDa; is composed, from N-term to C-term, of: a globular domain (amino acids 1-479), , a linker (480-523), and the heavy chain arm (524-1640); properties: binding site for ATPase in N term, binding of the light chain in the C-term, and trimerization domain in the C-term. Subunit of clathrin, a structural protein composed of 3 heavy chains (CLTC, CLTCL1), and 2 light chains (CLTA, CLTB), which assembly is mediated by CALM. Form cages. Component of the vesicles matrix originated from the plasma membrane or the golgi
Localisation vesicles
Function mediate endocytosis of transmembrane receptors.

Implicated in

Entity ? t(2;22)(p23;q11.2)- ALK
Note CLTCL1/ALK may in fact be cases of CLTC/ALK
Disease ? found in a case of ALK+ anaplasic large cell lymphoma
Abnormal Protein ? 2197 amino acids, 248-250 kDa; 1634 (nearly all the CLTCL1 protein) N-term amino acids from CLTCL1, fused to the 562 C-term amino acids from ALK (i.e. the entire cytoplasmic portion of ALK with the tyrosine kinase domain); cytoplasmic localization restricted to granules
Oncogenesis constitutive autophosphorylation
