Unsupervised hierarchical clustering using SRPX2 expression did not identify genotype or injury-specific clusters. Data demonstrate that SRPX2 expression in the hypothalamus is resistant to genetic deficiencies in the urokinase-system or to the hypothalamus-affecting TBI.

we show that mice lacking SRPX2 show a specific reduction in excitatory VGlut2 synapses in the cerebral cortex, while VGlut1 and inhibitory synapses were largely unaffected. SRPX2 KO mice also exhibit an abnormal ultrasonic vocalization ontogenetic profile in neonatal pups, and reduced preference for social novelty.

RefSeqs maintained independently of Annotated Genomes

These reference sequences exist independently of genome builds. Explain

These reference sequences are curated independently of the genome annotation cycle, so their versions may not match the RefSeq versions in the current genome build. Identify version mismatches by comparing the version of the RefSeq in this section to the one reported in Genomic regions, transcripts, and products above.

See identical proteins and their annotated locations for NP_001077364.2

Status: VALIDATED

Description

Transcript Variant: This variant (2) lacks an exon in the 5' UTR, compared to variant 1. Both variants 1 and 2 encode the same protein.The encoded protein contains an in-frame start site 41 codons upstream of the currently annotated site, but Kozak sequence considerations and the presence of a signal peptide in the shorter version make the shorter version the more likely protein product.
