Figure(s):Figs. 2, 3, 4, 5
Annotation description:Fig 2, 3, 4, 5 Molecular layer Golgi Cell dendrites and dendritic spines were labelled with anti-contactin-1 antibodies in immunoEM of 10-day old and adult mice.

Note that other neuron types exhibit presynaptic labeling (annotation 945), but that at no synapse both pre- and post-synaptic labeling was detected.

- Based on the known lipid anchor of the protein, the "anchored component of ... membrane" term was chosen.

Additional literature:A hydrophobic analysis of contactin-1 revealed a stretch of nonpolar amino acids at its extreme C-terminus, indicative of attachment to the membrane via a GPI lipid anchor. Expression of human contactin-1 revealed plasma membrane expression by immunostaining. @ PMID:7959734
