The subunits that make up the large, medium and small chains of adaptor proteins.

An adaptor protein complex found primarily on perinuclear compartments.

A clathrin adaptor protein complex primarily involved in clathrin-related transport at the TRANS-GOLGI NETWORK.

An adaptor protein complex primarily involved in the formation of clathrin-related endocytotic vesicles (ENDOSOMES) at the CELL MEMBRANE.

An adaptor protein complex involved in transport of molecules between the TRANS-GOLGI NETWORK and the endosomal-lysosomal system.

A family of large adaptin protein subunits of approximately 130-kDa in size. They have been primarily found as components of ADAPTOR PROTEIN COMPLEX 3.

A family of medium adaptin protein subunits of approximately 45 KDa in size. They have been primarily found as components of ADAPTOR PROTEIN COMPLEX 3 and ADAPTOR PROTEIN COMPLEX 4.

A class of proteins involved in the transport of molecules via TRANSPORT VESICLES. They perform functions such as binding to the cell membrane, capturing cargo molecules and promoting the assembly of CLATHRIN. The majority of adaptor proteins exist as multi-subunit complexes, however monomeric varieties have also been found.

A family of large adaptin protein subunits of approximately 90 KDa in size. They have been primarily found as components of ADAPTOR PROTEIN COMPLEX 1.

A family of large adaptin protein complex subunits of approximately 90-130 kDa in size.

A family of large adaptin protein subunits of approximately 100 kDa in size. They have been primarily found as components of ADAPTOR PROTEIN COMPLEX 2.

Single chains of amino acids that are the units of multimeric PROTEINS. Multimeric proteins can be composed of identical or non-identical subunits. One or more monomeric subunits may compose a protomer which itself is a subunit structure of a larger assembly.

A broad category of carrier proteins that play a role in SIGNAL TRANSDUCTION. They generally contain several modular domains, each of which having its own binding activity, and act by forming complexes with other intracellular-signaling molecules. Signal-transducing adaptor proteins lack enzyme activity, however their activity can be modulated by other signal-transducing enzymes

The main structural coat protein of COATED VESICLES which play a key role in the intracellular transport between membranous organelles. Each molecule of clathrin consists of three light chains (CLATHRIN LIGHT CHAINS) and three heavy chains (CLATHRIN HEAVY CHAINS) that form a structure called a triskelion. Clathrin also interacts with cytoskeletal proteins.

Macromolecular complexes formed from the association of defined protein subunits.

The process in which substances, either endogenous or exogenous, bind to proteins, peptides, enzymes, protein precursors, or allied compounds. Specific protein-binding measures are often used as assays in diagnostic assessments.

The fundamental dispositions and traits of humans. (Merriam-Webster's Collegiate Dictionary, 10th ed)

A subclass of clathrin assembly proteins that occur as monomers.
