一般說明

The gene TOP1 (DNA topoisomerase 1) is mapped to human chromosome 20q12-q13.1. The protein localizes in the nucleus.

免疫原

TOP1 (NP_003277, 692 a.a. ~ 765 a.a) partial recombinant protein with GST tag. MW of the GST tag alone is 26 KDa.

生化/生理作用

DNA topoisomerases cause single (type-1) or double (type-2) strand DNA breaks, leading to DNA relaxation. They control DNA replication, transcription, recombination and chromatin remodeling. TOP1 (DNA topoisomerase 1) binds to the promoters and thereby induces nucleosome disassembly, histone acetylation and gene expression. Camptothecin is a non-competitive TOP1 inhibitor. TOP1 also controls alternative splicing through phosphorylation of serine/arginine-rich proteins. It is up-regulated in non-small cell lung cancer (NSCLC).

外觀

Solution in phosphate buffered saline, pH 7.4

Lamellarin D (Lam-D) is a hexacyclic pyrole alkaloid isolated from marine invertebrates, whose biologic properties have been attributed to mitochondrial targeting. Mitochondria contain their own DNA (mtDNA), and the only specific mitochondrial topoisomerase in vertebrates is mitochondrial topoisomerase I (Top1mt).
