Rabbit Anti-AP36/FITC Conjugated antibody
background:
Clathrin-coated pits and vesicles are assembled for receptor-mediated endocytosis through interaction with Clathrin associated protein complexes. Vesicle transport is mediated from the trans-Golgi network by the adapter complex AP-1 and from the plasma membrane by the AP-2 complex. The AP-1 and AP-2 adapter protein complexes consist of Clathrin binding Adaptin proteins (g and b1 for AP-1, a and b2 for AP-2) and two smaller subunits known as AP50 and AP17. The a and b Adaptin chains have a similar two-domain organization with SLCterminal domains that vary in both sequence and length. a-Adaptin splice variants A and C display variable relative expression levels and differential distribution in different tissues. AP-3 (also designated AP36 or F1-20) is a synapse-specific Clathrin assembly protein. The protein CALM (Clathrin assembly protein lymphoid myeloid leukemia) is highly homologous to AP36 and may also be involved in Clathrin assembly.
Function:
AP36 is a clathrin binding phospho-protein and faciliates the formation of clathrin coats. This protein is also known as pp155, NP185, F1-20, and AP-3. During neurotransmitter release synaptic vesicles fuse with the presynaptic plasma membrane. A whole protein machinery consisting of amphiphysin, clathrin, endophilin and synaptojanin is involved in the subsequent endocytotic recycling of the synaptic vesicles.
Subunit:
Binds AP2A2. Interacts with AP2B1; clathrin competes with SNAP91 (By similarity).
Subcellular Location:
Component of the coat surrounding the cytoplasmic face of coated vesicles in the plasma membrane.
Post-translational modifications:
Thr-310 can be modified by the addition of N-acetylglucosamine which can be further phosphorylated. There is no evidence for direct Thr-310 phosphorylation (By similarity).
Similarity:
Contains 1 ENTH (epsin N-terminal homology) domain.
