Subunit of clathrin-associated adaptor protein complex 1 that plays a role in protein sorting in the late-Golgi/trans-Golgi network (TGN) and/or endosomes. The AP complexes mediate both the recruitment of clathrin to membranes and the recognition of sorting signals within the cytosolic tails of transmembrane cargo molecules. Involved in TLR3 trafficking. Source: Recombinant protein corresponding to aa1-104 from human AP1S3, fused to GST-tag at N-terminal, expressed in E. coli. Molecular Weight: ~40kD Amino Acid Sequence: MIHFILLFSRQGKLRLQKWYITLPDKERKKITREIVQIILSRGHRTSSFVDWKELKLVYKRYASLYFCCAIENQDNELLTLEIVHRYVELLDKYFGNTWPFARA Storage and Stability: Lyophilized and reconstituted products are stable for 6 months after receipt at -20C.
