Summary: Enables type II activin receptor binding activity. Involved in positive regulation of protein localization to cell surface; positive regulation of receptor internalization; and regulation of activin receptor signaling pathway. Acts upstream of or within Rho protein signal transduction; protein targeting; and regulation of endocytosis. Located in cell surface. Is expressed in several structures, including blood vessel; extraembryonic component; genitourinary system; neural tube; and retina. Orthologous to human SYNJ2BP (synaptojanin 2 binding protein).

The findings suggest that ARIP2 is widely distributed in various tissues and may be a negative regulator of activin action in pituitary cells.
Title: Expression and localization of activin receptor-interacting protein 2 in mouse tissues.
ARIP2 expression can be influenced by various factors. ARIP2 may participate in the negative feedback regulation of signal transduction in the late stage by affecting the expression of activin type 2 receptor.
Title: Regulation of activin receptor-interacting protein 2 expression in mouse hepatoma Hepa1-6 cells and its relationship with collagen type IV.
Overexpression of ARIP2 enhances endocytosis of ActRIIAs; data indicate that ARIP2 is a novel factor regulating cell surface ActRIIA expression and activin function.

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.

NM_001309814.1 → NP_001296743.1 synaptojanin-2-binding protein isoform 2

See identical proteins and their annotated locations for NP_001296743.1

Status: VALIDATED

Description

Transcript Variant: This variant (2, also known as ARIP2c) lacks an exon and its 3' terminal exon extends past a splice site that is used in variant 1. This results in a novel 3' coding region and 3' UTR, compared to variant 1. It encodes isoform 2 which is shorter and has a distinct C-terminus, compared to isoform 1.
