CC   -!- SUBCELLULAR LOCATION: Cytoplasm {ECO:0000269|PubMed:20376170}.
CC   -!- TISSUE SPECIFICITY: Expressed most abundantly in the brain at protein
CC       level. Present in cortex, cerebellum and midbrain. Found in neurons.
CC       Elevated expressions detected in Alzheimer brain samples. Also
CC       expressed in testis. {ECO:0000269|PubMed:20376170}.
CC   -!- MISCELLANEOUS: Originated from non-coding DNA sequences (insertion of
CC       repeat elements especially Alu). Seems to exist only in human.
