CLTC（clathrin heavy chain），癌症关联基因，基因ID：1213，氯氰菊酯是细胞内细胞器胞质表面的主要蛋白质成分，称为包被泡和包被坑这些特殊的细胞器参与受体的细胞内运输和多种大分子的内吞作用氯氰菊酯外壳的基本亚基由三条重链和三条轻链组成。[由RefSeq提供，2008年7月] Clathrin is a major protein component of the cytoplasmic face of intracellular organelles， called coated vesicles and coated pits. These specialized organelles are involved in the intracellular trafficking of receptors and endocytosis of a variety of macromolecules. The basic subunit of the clathrin coat is composed of three heavy chains and three light chains. [provided by RefSeq， Jul 2008]。
