Wnt-5a蛋白
Wnt-5a蛋白
P41221功能描述
七次跨膜受体卷曲家族成员的配体。根据受体环境,可激活或抑制典型Wnt信号通路。在FZD4存在下,激活β-连环蛋白信号通路。在ROR2存在下,通过涉及下调β-连环蛋白诱导的报告基因表达的GSK3非依赖性途径促进β-连环蛋白降解,从而抑制典型Wnt通路 (By similarity)。抑制典型通路允许软骨发生并抑制肿瘤形成。刺激细胞迁移。降低癌细胞的增殖、迁移、侵袭性和克隆形成能力,可能作为肿瘤抑制因子 (PubMed:15735754)。介导黑色素瘤细胞的运动 (PubMed:17426020)。胚胎发育过程中,为初级前后轴的延伸以及肢体和生殖结节的生长所必需。抑制软骨细胞中II型胶原的表达 (By similarity)。 {ECO:0000250|UniProtKB:P22725, ECO:0000250|UniProtKB:Q27Q52, ECO:0000269|PubMed:15735754, ECO:0000269|PubMed:17426020}。
组织特异性
Expression is increased in differentiated thyroid carcinomas compared to normal thyroid tissue and anaplastic thyroid tumors where expression is low or undetectable. Expression is found in thyrocytes but not in stromal cells (at protein level) (PubMed:15735754). Detected in neonate heart and lung (PubMed:8288227).
