Purity ~95% (SDS-PAGE). Microtubule-associated proteins 1A/1B light chain 3B, belongs to the MAP1 LC3 family. It is a subunit of neuronal microtubule-associated MAP1A and MAP1B proteins, which are involved in microtubule assembly and important for neurogenesis. MAP1LC3B may also be involved in formation of autophagosomal vacuoles. It is expressed primarily in heart, testis, brain and skeletal muscle. Source: Recombinant protein corresponding to aa1-120 of human MAP1LC3B, fused to His-tag at N-terminal expressed in E. coli. Molecular Weight: ~16.2kD AA
