In the full designation the cell type and nature and molecular weight of the antigen are given in brackets; for CD4, this is as follows: [T,gp55]. CD4 is present on a subset of T lymphocytes (helper\/inducer T cells) and is also expressed at a lower level on monocytes, tissue macrophages and granulocytes. The antigen is involved in binding to MHC class II molecules. The intracellular domain of the antigen is associated with p56lck protein tyrosine kinase.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eCellular localization (datasheet):\u003c\/strong\u003e Membrane; Single-pass type I membrane protein.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eTissue details (datasheet):\u003c\/strong\u003e Both mature cathepsin L1 and procathepsin L are found in the upper epidermis.
