Protein-coding gene in the species Homo sapiens
Cytoskeleton-associated protein 2 is a protein that in humans is encoded by the CKAP2 gene .[5] [6]
Human CKAP2 gene, the cDNA of which is known as LB1, is a cytoskeleton -associated protein involved in mitotic progression. Its high transcriptional activity has been observed in the testes , thymus , and diffuse B-cell lymphomas . The gene codes for a protein of 683 residues, which lacks a homology to known amino acid sequences. On evidence of immunofluorescence analysis, the CKAP2 product is a cytoplasmic protein associated with cytoskeletal fibrils.
The CKAP2 gene is in chromosome 13q 14. Rearrangements of this region result in various tumors. Thus deletions have been detected in multiple myeloma , prostate cancer , head-and-neck squamous-cell carcinoma , B-cell prolymphocytic leukemia , non-Hodgkin lymphoma , and in more than half cases of B-cell chronic lymphocytic leukemia .
