[求助] 求研究蛋白质结构和功能的大侠指点

RECS1 is a novel shear stress-responsive gene that encodes a protein putatively forming seven-span transmembrane domains. We reports here that mouse RECS1 (mRECS1) transcripts is detected in most tissues except for thymus, spleen and testis. The putative cytoplasmic N-terminus of mRECS1 has a high content of proline (23%) and glycine (12%) residues, contains one PPXY motif, multiple PXXP motifs and one overlapping P(T/S)AP and PPXY motif (P(T/S)APPXY). The PPXY motif lies within one potential PEST sequence (PEST score: +7.65). We prepared anti-RECS1 polyclonal antibody and found by western blot analysis that the mRECS1 protein in the lung and aorta was detected as a 34.4 kDa band. However, one shifted 58 kDa band or three shifted bands (48, 69, 82 kDa) were detected in the heart or the liver, respectively. Since northern blot detected only one species of mRECS1 mRNA in heart and liver tissues, as well as other tissues (approximately 2.2 kb), these differences in molecular weight seem to be due to posttranslational modification. Biochemical fractionation and RECS1-GFP fusion protein revealed that RECS1 localizes at the endosomal/lysosomal membranes in the cytoplasm. To understand the function of RECS1 in the body, we made RECS1 knockout (KO) mice and found that RECS1 KO mice (older than 14 months) are prone to cystic medial degeneration (CMD). Taken together, we conclude that RECS1 is an endosomal/lysosomal membrane protein which plays protective roles in vascular remodeling.

请问从这个蛋白的结构来讲它有没有可能是一个激酶或者可能和那些蛋白结合,或者和含有哪类结构域的蛋白结合?谢谢!

RECS1 的 HGNC 名字是 TMBIM1,transmembrane BAX inhibitor motif containing 1,和细胞凋亡有关,肯定不是激酶。可能和细胞凋亡有关的蛋白结合。数据库有以下相互作用数据:
