ab254362 was shown to react with aTXN2 in wild-type HAP1 cells in Western blot with loss of signal observed in a ATXN2 knockout cell line. Wild-type HAP1 and ATXN2 knockout cell lysates were subjected to SDS-PAGE. Membranes were blocked in 5% milk in TBST for 1 hr before incubation with ab254362 overnight at 4 °C at a 1/1000 dilution. Blots were incubated with goat anti-rabbit HRP secondary antibodies at before imaging. These data were provided by YCharOS Inc., an open science company with the mission of characterizing commercially available antibody reagents for all human proteins.

Supplementary information

SCA2 also known as Spinocerebellar Ataxia Type 2 refers to a protein primarily affected by mutations in the ATXN2 gene. It weighs around 150 kDa. SCA2 expresses predominantly in the brain with significant presence in Purkinje cells of the cerebellum as well as regions like the thalamus and hippocampus. It functions as an essential component within neuron-specific structures and may associate with RNA processing events.
Biological function summary

SCA2 shows significant interactions within the neuronal RNA processing machinery. This protein is part of a large complex involved in regulating RNA stability and translation. Its role contributes significantly to maintaining neuron function and viability affecting synaptic signaling and plasticity which are critical for cognitive processes and motor control. SCA2 influences neural communication through modulation and degradation of messenger RNAs.

Pathways

SCA2 plays a role in the mRNA metabolic process related cellular pathways. It interacts in pathways like RNA transport and degradation linking it functionally to proteins such as TDP-43 and FUS which also have prominent roles in RNA processing. These associations support communication across neurons and ensure accurate protein synthesis necessary for neuronal health and function.

Malfunction or mutation in SCA2 relates directly to spinocerebellar ataxia type 2 a degenerative disorder affecting movement. The imbalance in related pathways often leads to pathological changes contributing to dysfunctions in Ataxin-2 often seen alongside interactions with proteins like Huntingtin which elucidate its involvement in neurological diseases. Such connections imply a substantial impact on neuronal survival and disease progression.
