Background: Semaphorin 3G

Semaphorin 3G (Sema3G), also known as Semaphorin sem2, is a class 3 member of the semaphorin family initially identified as regulators of neuron-axonal guidance (1, 2). More than 30 semaphorins have been discovered and are divided into eight classes: classes 1 and 4–7 are membrane-associated, while classes 2, 3, and 8 are in a secreted form (1, 2). Mature human Sema3G consists of an N-terminal sema domain, a plexin-semaphorin-integrin (PSI) domain, an Ig-like C2-type domain and a C-terminal basic domain (3). Within the extracellular domain, human Sema3G shares 87% amino acid sequence identity with mouse and rat Sema3G. In vitro analysis shows Sema 3G binds to Neuropilin-2, which forms a receptor complex with Plexin-D1. Via this pathways Sema 3G controls lymphatic vascular patterning by the means of cellular collapse (4). It shows protective effects in ischemic retinopathies by coordinating interactions of beta-catenin and VE-Cadherin in endothelium (5). Sema 3G has been shown to be involved in adipocyte differentiation. Knockdown of Sema3G inhibited weight gain through PI3K/Akt/GSK3 beta signaling in the adipose tissue and the AMPK/SREBP-1c pathway in the liver. Thus, Sema 3G is an adipokine essential for adipogenesis, lipogenesis, and insulin resistance and is associated with obesity (6).
